BOUNDARIES
& BORDERING COUNTRIES
Pakistan
came into existence on 14 August 1947 as an independent and sovereign state. Pakistan
occupies a key position in a strategic location. Located in South Asia, Pakistan lies
between 23 degrees 30 minutes and 36 degrees 45 minutes north latitude, and between 61
degrees and 75 degrees 31 minutes east longitude. Pakistan stretches 1,600 kilometers
north to south and about 885 kilometers east to west, covering a total area of 796,095
square kilometers (310,403 square miles).
Afghanistan
is situated to the west of Pakistan along a border of 1,400 miles long. The boundary
agreement between Afghanistan and the British Indian Government was signed on 12 November
1893. Since then, the border has been known as the Durand Line.
China
is situated to the north. Pakistan's Northern Areas, consisting of Baltistan, Gilgit and
Hunza, have a long common border with the Chinese province of Siankiang. The border runs
from the Pamir tri-junction of Afghanistan, China, and Pakistan to the Karakoram Pass and
was demarcated by a Sino-Pakistan Boundary Agreement of 2 March 1963.
To
the east is the Indian territory of East Punjab and Rajasthan, with a common border about
1,610 kilometers long. It is a very long border with no natural barriers, such as rivers
or mountains, to separate the territories of these two independent neighbours, a border
agreement was signed on 1 January 1960.
Iran
is situated to the west, south of Afghanistan. The border is about 590 miles long and runs
from Koh-i-Malik Siah, the trijunction of Afghanistan, Iran and Pakistan, to Gawader Bay
in the Arabian Sea. A boundary accord between Iran and Pakistan was signed in 1960. To the
south of Pakistan is the Arabian Sea. |

COASTLINE
Pakistan
has only one coastline, which stretches along the Arabian Sea ; the Makran coast, it is
Balochistan's southern strip and stretches for 754 kilometers (470 miles) along the
Arabian Sea. The distance in a direct line, however from Karachi (Sindh) to Gwadur Bay
(Balochistan) is about 335 miles (543 kilometers), and from Karachi to Sir Creek (Rann of
Kutch) is about 211 kilometers (135 miles).
Long,
sandy beaches, rugged promontories, and tidal creeks characterize the coastline. Three
ranges of hills rising to over 1,500 meters (5,000 feet) run parallel to the coast: the
Coastal Makran Range, 30 kilometers (20 miles) inland; the Central Makran Range, 130
kilometers (80 miles) inland; and the Siahan Range, 200 kilometers (125 miles) away from
the sea.
There
is very little rain in the Makran region; the few villages and towns along the coast and
between the hills are sustained by spring water. The rivers are generally filled by floods
after the occasional heavy rains. Owing to scanty rainfall, the saline nature of the soil,
and the physical conformation of the land, the shore is almost entirely desert, presenting
a succession of arid clay plains impregnated with saline matter and intersected by
watercourses. The most characteristic feature of the coastline is the repeated occurrence
of promontories and peninsulas of white clay cliffs, table-topped in form. The
intermediate tract is low, and in some places has extensive salt water swamps behind it.
The chief ports on the coast are Sonmiani or Miani, Pasni, and Gwadar.
The
Makran coast is of great historical importance. Alexander the Great marched half his army
home along the Makran coast in 325 BC, and Muhammad Bin Qasim came from Baghdad to Sindh
through Makran in 711 AD. The Makranis stood firm against the Mughals, but bowed nominally
to the British Raj.
Turbat
is the divisional headquarters of Makran. It is only since 1971 that some effort has been
made to develop the region. There is no road along the coast, but daily flights connect
the three main coastal towns of Pasni, Gwadar, and Jiwani with Karachi.
Gwadar
and Jiwani belonged to Oman for about 200 years. The Khan of Kalat gave them as a present
to the Sultan of Oman in the 18th century. In 1958 they were sold back to Pakistan by
Sultan Qaboos bin Saeed of Oman for 10 million dollars. |

DESERTS
CHOLISTAN
An
extensive area in the southwest of Pakistan, Cholistan is covered with rolling sand plains
and dunes. It is an area separated from the Indus valley by the dry channels of the
Ghaggar River in the Punjab. Lying between Thar on the west and Rajputana on the
southeast, this extensive desert is called Cholistan or Rohi.
The
desert of Cholistan extends over 10,399 square miles and includes two-thirds of the former
state of Bahawalpur. It is in fact an extension of the Thar desert, whose western edges
are formed by the ancient river called the Hacra. Cholistan region can be divided into two
parts: Greater Cholistan and Lesser Cholistan.
Greater
Cholistan, in the south, stretches over an area of 700 square miles. The dunes, or tibbas, can rise as high as several hundred feet in
the southern quarter, while in Lesser Cholistan, which stretches over 3000 square miles,
the dunes are low. Salt flats occur among the sand throughout Cholistan. They can stretch
for several miles or be as small as a few hundred yards each. Flash storms convert them
temporarily into lakes, and the runoff is collected in natural depressions or man-made
ponds called tobas. Receiving five inches of
rainfall a year, this region is not drained by any perennial stream. Therefore, the
topography has been formed mainly by the wind. The only other sources of water are wells,
which are rare in Cholistan.
Given
these circumstances, the population is nomadic, moving from one water hole, or toba, to the next. When these dry up, they migrate
to the semi-permanent settlements around the wells; in extreme draught they move to the
permanent settlements at the edge of the desert.
The
climate of this desert region is as hot as 1250F (or above) in summer;
winters are cold. The annual rainfall is four to five inches, and the rainy season lasts
from July to August.
THAR
The
district of Tharparkar consists of two distinct parts called Thar (the desert) and Parkar
(the small hilly tract in the extreme southeast). It was first known as Thar Parkar
districts but subsequently became Tharparkar in 1920.
It
lies in Sindh between 240-10/ to 250-44/ north latitude and 680-55/ to 710-05/ east longitude. It is bounded on the north by
Sanghar District, on the west by Hyderabad District, on the south by the Rann of Kutch and
on the east by Marwar (India). The desert area to the east consists of barren tracts of
sand dunes covered with thorny bushes. There are also lakes in the desert area, of which
the largest is Saran which supplies salt to the entire district. It provides revenue to the government and work for
the people. Minerals such as raper-khar or chambo used as washing soda are also found in the
desert.
The
common plants of the desert area are thukar, phog (Calligonum
polygonoeides), ak (Calotropes gigantea), buh, khabai, mural, kandi (Prosopic speugeras), baneri and rohiro.
Thar
has a tropical desert climate, and April, May and June are the hottest months. The mean
maximum temperature during this period is 410C. December, January and
February are the coldest months. The mean maximum and minimum temperatures during this
period are 280C
and 90C
respectively.
Rainfall
varies from year to year. Most of the rain occurs in the monsoon months between June and
September. The winter rains are insignificant, while April, May, October and November are
completely dry. Famines are quite frequent in the desert when there are no rains. The Thar
is entirely dependent on rainfall, and the country becomes picturesque with green patches
on sand dunes after the rains. Jawar and bajra are the main crops grown in the desert, but
when the rain fails, the inhabitants migrate to the irrigated portion of the district and
earn their livelihood by labour and return home when the next rainy season approaches.
In
the desert, dangerous snakes such as khapar,
cobra, plain, lundi and other snakes are
generally found in the rainy season in great numbers. Many deaths are caused by snake
bites. There are also black scorpions.
Hyena
and lynx are found, mostly where the desert meets the Rann of Kutch. Another animal is the
gorkhar (wild ass) used for carrying baggage.
In the interior of the desert, camels are the only means of transport and of ploughing the
land. |

FORESTS
Natural
vegetation comprises forests, shrubs, and grasses and is determined by climatic conditions
and soil types. The climate of Pakistan is too dry for forests, except in the northern
hilly and sub-mountainous belts.
Wood
cutting, overgrazing, and the annual removal of grass cover from the slopes are all
processes which handicap soil formation and the development of forests. As a result, there
is a marked deficiency of tree cover in Pakistan. For a balanced economy, with an agrarian
base, 20-25 percent of the land should be under forest. In Pakistan, Only 4.8 percent of
the total area is forested. Of the 2.8 million hectares classified as forests in 1980,
Punjab had 0.3 million, Sindh 0.6 million, NWFP 1.4 million, Balochistan 0.1 million, and
the remaining 0.4 million were in Azad Kashmir. In addition, there are 1.7 million
hectares of scrub land and 6.1 million of range land in the country. Over two-thirds of
the forest land is under public ownership; the remainder is privately, owned. Forests are
classified as "reserved," "protected," or "unclassified."
Reserved
and protected forests are publicly owned. Tree felling in Reserved forests is done only
under the strict supervision of the Forest Department. In protected forests, the local
population has some traditionally acquired rights of use, for example, grazing and
collecting dried branches for firewood. Unclassified forests, under private or communal
ownership, are so badly depleted that large areas of such so-called "forests"
are devoid of tree cover. The forests of Pakistan can be divided into six groups.
North And Northwestern Mountainous
Forests
The
annual rainfall in the northern and northwestern mountains is a little more than 100
centimeters, adequate for the growth of evergreen mountain trees. The forests on these
mountains consist of evergreen trees with pointed leaves. These trees rise to a great
height, but it takes them fifty to sixty years to grow to their full size. In winter,
severe cold checks their growth. They are softwood forests. The principal coniferous trees
include fir, deodar, blue pine, and spruce. They grow generally at altitudes of 900-3800
meters. Above the tree line 3,800 meters, there are stunted alpine forests.
Chestnut
and walnut trees found in the mountains shed their leaves in winter. The lower slopes of
the mountains are covered with forests of cherry, poplar, and other broadleaf trees.
Forests of this kind are located in the districts of Rawalpindi, Abbottabad, Mansehra,
Malakand, Dir, Swat, and Chitral. Deodar, kail, spruce, and fir are some of the most
important trees of this region. Transportation of wood from these mountains to the plains
below is difficult and costly. This is one reason why timber is so costly in Pakistan.
The
climate of the region is suitable for plantation of poplar, willow, and eucalyptus. These
trees grow fast and are a good source of low-grade timber.
Submountainous Shrub Forests Of The
Foothills And Plains
Below
900 meters there are some pines, but more broadleaf trees, such as oak, maple, birch,
walnut, and chestnut. Submountainous forests are found in Gujrat, Jhelum, Rawalpindi,
Mardan, Peshawar, Kohat, and Attock Districts. They consist of phulai, kahu, jand, and
blackberry. The hard wood of these trees is generally used for fuel and house
construction. In these areas, mulberry, willow, poplar, shisham, eucalyptus, teak, and
other trees can also be planted.
Western Dry Mountainous Forests
(Balochistan Hills)
In
Quetta and Kalat Divisions of Balochistan there are some dry hill forests at altitudes
between 900 and 3,000 meters. The trees include chilghosa, pine, and pencil juniper. In
1972-73, a small beginning was made to improve the forests of Balochistan by stabilizing
the sand dunes in Pasni and Gwadar and planting trees along 250 kilometers of highway. In
Dera Ghazi Khan, Rajanpur, and Dera Ismail Khan Districts, poplar, mulberry, and dharek
can be grown with some effort.
Riverain Bela Forests And Irrigated
Plantations
These
forests have been planted in areas where canal water is abundant. The most important of
these are Changa Manga, Chichawatni, Khanewal, Burewala, Thal, Shorkot, Bahawalpur,
Sukkur, Taunsa, Guddu, and Kotri. In these areas, high-yielding commercial units of
hardwood species have been planted with shisham, mulberry, and acacia trees. Shisham is a
high-quality cabinet wood extensively used for furniture.
Changa
Manga forest near Lahore is the largest of the irrigated forest plantations. First
established about a hundred years ago, it now cover 5,000 hectares and has an annual yield
of 0.7 cubic meters of timber and 17 cubic meters of firewood per hectare. This yield is
some ten times that of the natural forests in Pakistan.
Other
sizeable irrigated plantations are Wan Bachran in the Thal area, Chichawatni in Sahiwal
District, and some parts of Ghulam Muhammad Barrage and Guddu Barrage. Linear plantations
are found along river banks, irrigation canals, roads, and railways.
The
planted area is still relatively small. In Punjab, of a total forested area of 0.3 million
hectares, only 122,000 hectares are irrigated, while 3,000 hectares is linear plantations.
The Rakhs
The
Rakhs are dry scrub forests grown in small patches on the arid plain. They provide
insignificant quantities of fuel wood. Species include farash, bakin, jand, and karil.
Tidal Or Coastal Forests
These
occur in the coastal wastelands from Karachi to Sir Creek, (Rennof Kutch) covering an area
of about 300,000 hectares. As the coastal areas are submerged by the high tide twice a
day, only coconut and grass grow in these salt water forests. |

GLACIERS
A
glacier is defined as a slowly moving river or mass of ice. Pakistan has more glaciers
than any other land outside the North and South Poles. According to a recent survey, there
are 1,214 glaciers in Pakistan. The glacier area lies among the valleys of the Karakoram
and Hindukush Ranges and at the base of Nanga Parbat in the Himalayas. Pakistan's glacial
area covers some 13,680 square kilometers which represents an average of 13 percent of the
mountainous regions of the Upper Indus Basin.
Pakistan's
glaciers can rightly claim to possess the greatest mass and collection of glaciated space
on the face of earth. In fact, 37 percent of the Karakorams are under glaciers as compared
with the Greater Himalayas (17 percent) and the European Alps (22 percent). The
Karakorams' southern flanks (east and west of the Biafo Glacier) have a concentration of
glaciers which works out to 59 percent of their total area.
Baltoro Glacier
Baltoro
Glacier is one of the largest glaciers of the world, with an area of 529 square kilometers
and 62 kilometers in length. This glacier, fed
by some 30 tributaries, constitutes a surface area of 129.39 square kilometers (471 square
miles). Here, one can see four of the fourteen highest peaks in the world, over 8,000
meters above sea level.
Batura Glacier
Hunza
Valley is the abode of a large number of glaciers. The most famous among them is Batura
Glacier, the fifth longest glacier in the world, with an area of 220 square kilometers and
56 kilometers in length. Some other important glaciers are:

Biafo Glacier
Biafo
Glacier is a huge river of ice 63 kilometers long, with an area of about 383 square
kilometers. It descends from the central peaks of the Karakorams, having its snout at
Khurdopin and flowing eastward into Braldu Valley about 10 kilometers east of Askole. The
glacier is guarded from either side by massive granite peaks.
Hispar Glacier
Hispar
Glacier covers an area of 343 square kilometers and has a length of 49 kilometers. It is
one of a groups of four mountain glaciers surrounded by many smaller ones lying in a
parallelogram. Part of Hispar Glacier lies in Nagar state in Gilgit Agency. Hispar joins
the Biafo Glacier at an altitude of 5,154 meters (16,910 feet) to form an ice corridor
115.87 kilometers (72 miles) long.
Siachin Glacier
On
the basis of recent estimates Siachin is the largest glacier in the world, which is 71 kms
long and covers an area of 685 sq.kms. It is situated in the Karakoram. |

LAKES
Chitral Valley Lakes
In
Chitral Valley there are two lakes of considerable interest. One is at Shandur, 4,267
meters (nearly 12,000 feet) above sea level at the Gilgit Agency border. It is about 3
kilometers (2 miles) long and about 244 meters (800 feet) wide.
Gilgit
And Hunza Valley Lakes
In
Gilgit and Hunza Valley there are as many as twelve lakes, large and small: Phandar (3,040
meters/10,000 feet), Rama (4,267 meters/12,000 feet), Naltar (3,505 meters/10,500 feet),
Gudai (2,438 meters/8,000 feet), and Bariot (3,352 meters/11,000 feet). Bariot Lake is the
famous destination for the fabulous migratory Siberian ducks. There are a number of other
lakes in the region, including Jutial, Palogabpuin, Shimshal, Minapin, Teo, and Darkush.
Hanna Lake
Hanna
Lake is 10 kilometers from Quetta. Goldfish in the lake come swimming right up to the
edge. A little distance away, the waters of the lake take on a greenish-blue tint. Right
where the water ends, pine trees have been planted on the grassy slopes. The greenish-blue
waters of the lake provide a rich contrast to the sandy brown of the hills in the
background.
Katchura
Lake
In
the Baltistan Valley there are three beautiful lakes: Upper Katchura, Katchura, and
Satpara. Upper Katchura is 25 miles from Skardu and Katchura is 26 kilometers 18 miles
from Skardu.
Katchura
Lake is a shimmering, peaceful, deep blue stretch of water 2,286 metres about 7,500 feet
above sea level. Throughout the summer, many exotic and colourful flowers decorate its
banks. White peach, apricot, and apple trees are laden with blossoms, ripening into fruit
in the early autumn. Katchura apples enjoy a very high reputation all over the world. The
lake offers great opportunities for trout fishing.
Keenjhar Lake
Keenjhar
Lake, formerly Kalri Lake, is one of Karachi's sources of water. About 32 kilometers 20
miles long and 10 kilometers 6 miles wide, it has also been developed as a resort and
offers sailboats for hire, fishing facilities, and bird watching. The National Highway to
Hyderabad follows the west bank of the Indus across rich farmland irrigated by water from
Keenjhar Lake.
Lalusar Lake
Situated
in Kaghan Valley, Lulusar Lake is 48 kilometers 30 miles from Naran. It ripples at an
altitude of 4,570 meters 15,000 feet with a rim of patterns in blue and gold reflecting
the riotous colours of wildflowers on its banks. It is the main source of the River
Kunhar, which flows down the meandering Kaghan Valley. There is plenty of trout fishing
for the sporting traveller.
Manchar Lake
Manchar
is a beautiful, picturesque lake. "Man"
means "jewel," while "char"
means "an expanse of water." The lake is oval in shape, extending northwest to
southeast for about 10 miles with an average breadth of about 3 miles. Its depth varies
from 8 to 16 meters.
After
the rains, the lake doubles in length and width. In the dry season, the area of the lake
is 30 square miles after the rains, the lake spreads across an area of 200 square miles.
The lake is fed by the Nara and Aral Rivers. According to tradition, the lake is a bathing
place for fairies and mermaids. There are several small islands in the lake. The main
islands are Lal Chatto and Mashak. The lake is also famous for fowls and fishes.
Qarumbar Lake
Qarumbar
Lake is at Baroghal, 3675 meters (about 12,000 feet) above sea level.
Rawal Lake
Rawal
Lake is a large artificial reservoir catering for the water needs of Rawalpindi. The area
around the lake has been planted with flowering trees and laid out with gardens, picnic
spots, and secluded paths. The best places to picnic are on the far side of the lake,
which also offers boating and fishing. To the west of the lake is the Islamabad Club,
which offers different sporting facilities.
Saiful Muluk
In
the mountains and valleys of Pakistan, there are some picturesque lakes no less fabulous
than the mountains around them. Situated at very high altitudes ranging from 2,133 meters
(7,000 feet) to 4,267 (14,000 feet) above sea level, these lakes are marvels of nature
which have no parallel anywhere in the world. In fact, there are scores of lakes which are
inaccessible. Several are larger than Saiful Muluk, but they are invisible from November
to June, when they remain covered by snow.
Saiful
Muluk is situated at an elevation of 10,200 feet. About 10 kilometers (6 miles) from
Naran, the lake, one kilometer (half a mile) long, holds a perfectly clear mirror to the
nearby Malika Parbat (Queen of the Mountains,) 5,180 metres (17,000 feet) high. Saiful
Muluk offers excellent trout fishing.
There
is a charming legend attached to the lake about a handsome prince called Saiful Muluk who
fell in love with a fairy of the lake. He married the fairy, but when her demon lover
appeared, he became angry at seeing the happy couple and flooded the entire valley in
revenge. Of the fairies in the lake, some say they have deserted the place, while others
believe they still come to dance at night, recounts the 1907 Gazetteer.
Satpara Lake
Satpara
Lake is situated in Baltistan Valley. It is about 10 kilometers (6.5 miles) north of
Skardu, surrounded by snowy mountains which are mirrored in every beautiful detail in the
lake's crystal clear waters.
The
lake has a fairy tale island in the middle which can be reached by country boats one can
hire for the thrill of rowing. The lake also abounds in fish and it is considered an ideal
spot for fishing.
Swat Valley Lakes
There
are three lakes in Swat Valley:
Mahodand,
near Ushu, is approachable only on foot. It is a small but extremely beautiful lake amidst
a lush green plain.
Beshigran
Lake is about 20 miles east of Madyan.
Kundal
Lake, at a height of 10,500 feet lies northwest of Bahrain. It is the origin of the Uthrot
River and is approachable from Uthrot Valley.
Tarbela Lake
Tarbela
Lake is 91 kilometers (57 miles) long and can hold 11 million acre feet of water, enough
to cover 11 million acres of land to a depth of one foot. The maximum depth of the lake is
about 110 metres. |
|
MOUNTAIN RANGES
There
are two mountain groups in Pakistan, the northern mountains and the western mountains. The
northern mountains include the Himalayan, the Karakoram, and the Hindukush Ranges.These
high-altitude mountains are difficult to cross. A few passes link them, but due to heavy
snowfall, traffic ceases during the winter months. This is why neighbouring countries to
the north have had little effect on Pakistani culture.
The
northern mountains act as both a climatic and physical barrier and sometimes demarcate
international borders. During the winter, these mountains protect the plains from cold
winds Central Asian winds. They also intercept the summer monsoon winds coming from the
Arabian Sea and the Bay of Bengal, causing rains in Pakistan. In spring and summer,
snow-melt from the northern mountains feeds water into Pakistan's rivers. The Indus is one
of several rivers and tributaries which cut across these ranges. During the rainy season,
they carry enormous quantities of water which is used for irrigation and hydroelectric
power production.
On
the rainy southern slopes of these ranges are found magnificent and very valuable forests
of timber, as well as cultivated fruit trees. The mountains have a number of health
resorts, and in some places, precious minerals have been found.
Himalayas
The
word "Himalaya" is taken from the Sanskrit language, in which "hima"
means snow and "alaya" means abode. To the early geographers, these mountains
were known as Gmaus and Himaus or Hemodas, and there is reason to believe that these names
were applied to the western and eastern parts respectively, with the source of the Ganges
being taken as the dividing line. The Himalayas include the highest mountains in the
world, with more than 30 peaks rising to a height of 7,300 metres (24,000 feet) above sea
level.
Although
historically, the main Himalayas acted as a barrier to human movement, their offshoots
remained "half open," occasionally letting foreign influences into the
subcontinent. The Himalayas stretch uninterrupted for 2,500 kilometers 1,550 miles from
west to east, between Nanga Parbat 26,660 feet in the disputed state of Jammu and Kashmir
and Namcha Barwa 25,445 feet in Tibet. The Himalayas are bordered to the northwest by the
Hindukush and Karakoram Ranges and to the north by the high plateau of Tibet. The width of
the Himalayas from south to north varies between 125 and 250 miles. Their total area
amounts to about 594,400 square kilometers (229,500 square miles).
Though
India has sovereignty over most of the Himalayas, Pakistan and China occupy parts of them.
In the state of Jammu and Kashmir, Pakistan has administrative control of 32,362 square
miles of the range lying north and west of a ceasefire line established between India and
Pakistan in 1948. China occupies 14,000 square miles in Ladakh District of Kashmir, as
well as territory to the south of the McMahon Line, a 1914 boundary line limiting Tibetan
sovereignty in the Assam Himalayas of north east India.
From
south to north, the Himalayan ranges can be grouped into four parallel longitudinal
mountain belts of varying widths. They are designated as the Outer or Sub-Himalayas; the
Lesser or Lower Himalayas; the Great or Higher Himalayas; and the Tethys or Tibetan
Himalayas. The most important peaks of the Himalayan Range are Dhaulaigri 26,810 feet, Mt.
Everest 29,028 feet and Lhotse 27,923 feet.
The
Telhati Hills rise in the north and northwest, where the Upper Indus Plain ends. These
hills range from 100 to 320 metres. They are also called the Shiwalik Hills. The average
height of the Lesser Himalayas is 5,000 metres. Most of Pakistan's northern hilly area is
situated in the Lesser Himalayas, including hill resorts like Murree, Ayubia, Nathiagali,
Abbottabad, and the Kaghan Valley. The highest range of the Lesser Himalayas is Pir
Panjal.
The
average height of the Greater Himalayas is 6,500 metres. They remain covered with snow all
the year round. Their highest peak is Nanga Parbat, rising to a height of 8,250 metres
above sea level. The valley of Kashmir lies between Pir Panjal and the Great Himalayas.
Pakistan's mighty River Indus originates from these mountains. The important glaciers of
the Himalayas are Rongluk Glacier, Kyetrak Glacier and Kangchonjuro Glacier.
The
Himalayas are drained by 19 major rivers,of which the Indus and Brahmaputra are the
largest. The Himalayas, as a great climatic divide affecting air and water circulation
systems, exercise a dominating influence upon meteorological conditions in the Indian
subcontinent to the south and in the Central Asian highlands to the north. At places such
as Skardu, Gilgit, and Lek in the Indus Valley to the north of the Greater Himalayas, only
3-6 inches of rainfall occurs every year. The rocks of the Sub-Himalayan ranges are rich
in animal fossils.
Hindukush
International
boundaries running through the Hindukush are primarily those of Pakistan and Afghanistan.
Karamber Pass lies about 40 miles west of the Chinese border, while to the west, the
Hindukush Range approaches the border between Afghanistan and Iran without extending into
Iranian territory. The Hindukush Rnage lies between the Indus and Kabul Rivers. The
average height of this range is to 10,000 to 16,000 feet above sea level. Most of the
mountains remain snow-covered during the winter. The Kabul, Swat, Panjkore, and Kunar
Rivers flow through the minor ranges before joining the Indus from the Western side.
The
Pakistan-Afghanistan border follows the main watershed of the Hindukush Range throughout
its eastern region, from Lupsuk peak just south of Tirchmir, the highest peak of the
Hindukush. Tirchmir is in the north, and the mountains around it are capped with perpetual
snow and ice. Their height decreases southward in Mohmand Territory and the Malakand Hills
to only 5,000-6,000 feet. From the Dorah Pass, the boundary leaves the main watershed and
follows minor spears until it crosses the Kabul River, continuing along the crest of the
Safed Koh Range toward the south.
Three
main sections of the Hindukush may be defined. These are the Eastern Hindukush, which runs
from Karambar Pass in the east to Dorah Pass, not far from the Tirchmir; the Central
Hindukush, which continues to Khawak Pass, north of Kabul; and the Western Hindukush, also
known as the Koh-i-Baba, which gradually descends to the Kirmu Pass.
Important
peaks of the Hindukush Range are Tirchmir, Noshaq, and Anjuman, and the major glacier is
Chiantar. The range separates two major Asian climatic zones. They form a barrier to the
movement of winds. In summer, rain-bearing winds coming from the Bay of Bengal and the
Arabian Sea cannot cross these mountains, and so they cause rains in Pakistan and India.
In winter, severely cold winds blowing from Central Asia are stopped by these mountains
from reaching the plains of Pakistan.
The
southern slopes receive heavy rainfall and consequently are covered with forests of
deodar, pine, poplar, and willow. The more northerly ranges and north-facing slopes
receive practically no rain and are therefore barren.
There
is a considerable traffic from the mountains to the plains in winter and from the plains
to the mountains in summer. The permanent settlers grow corn, maize, barley, wheat, and
rice on terraced fields and also raise orchards of apples, apricots, peaches, and grapes.
Karakorams
Karakoram
is a Turkish word meaning "black pebbles," which hardly describes these shining,
white-clad peaks, although there are black rocks at the Karakoram Pass. The mountains of
the Karakoram Range rise to the northwest of the Himalayas. The Karakorams extend from
north of Kashmir to Gilgit. The average height of the range is 7,000 metres. The highest
peak in the range is K-2 (Godwin Austin), at 8,611 metres the second highest mountain in
the world. Thus it was the first in this area to attract mountain climbers. T. G.
Montgomery first measured this mountain from a high point near Kashmir in 1857. Convinced
of its extraordinary height, he called it K-2 (Karakoram-2), the mountain's survey number.
His calculations proved it to be the second highest mountain in the world. In 1861, climber, Godwin Austin approached K-2
peak. Some people wanted to name it Mt. Godwin Austin, but others thought it wrong to name
it after an individual, so its survey number, K-2, became its official name. Locally, it
is called Chagori.
A
recent geological report speculates that over the next 100 years, the height of K-2 will
approach that of Everest, the highest peak in the world. The calculation is based upon the
phenomenon of the upthrust of land, which could result in a gradual rise in height of the
mountain. A study commissioned in 1991 declared K-2 the world's most polluted mountain
because of trekkers and climbers who leave behind empty bottles, food containers,
polyethylene bags, and other trash.
The
Karakorams, along with the Pamirs, the Hindukush, the Kun Lun, and the Himalayas,
intersect to form a complex geographical feature known as the Pamir Knot. Together with
the Himalayas, the Karakorams account for 96 of the earth's 109 highest mountains.
Baltistan alone contains 10 of the world's highest peaks. The area not only boasts some of
the finest alpine sights in the world, but is also home to the greatest extent of glaciers
outside the polar regions.
Of
the world's 14 peaks exceeding 8,000 meters five are in Pakistan. These are situated at
the head of Baltoro Glacier in the Karakorams. They are K-2 (8,611.5 meters/28,253 feet),
Broad peak (8,046.72 meters/26,400 feet), Gasherbtum-I (8,068 meters/26,360 feet),
Gasherbtum-II (8,034.52 meters/26,360 feet), and the Hidden Peak (8,068 meters). In the
Lesser Karakorams, there are also such great peaks as Rakaposhi (7,788 meters/25,552
feet), scores of peaks of 7,000 meters (22,966 feet), and hundreds of nameless summits
below 6,096 meters (20,000 feet).
The
valley of Gilgit lies between the Karakorams and the Hindukush. The Karakoram Highway,
which passes through these mountains, is the highest trade route in the world. The KKH can
be justifiably called the eighth wonder of the world. It took almost 20 years of planning
and execution. Construction of the highway, 774 kilometers long, involved blasting almost
30 million cubic yards of rock and earth and required the use of over 8,000 tons of
explosives and 80,000 tons of cement. Approximately 15,000 men of the Pakistan Army and
Chinese workers were involved in its construction. About 408 Pakistanis and Chinese were
killed in the process. This road links Pakistan with China and is accessible through
Gilgit.
The Western Mountains
The
western low mountains spread from the Swat and Chitral Hills in a north-south direction
(along which Alexander the Great led his army in 327 BC) and over a large portion of the
North West Frontier Province. North of the Kabul River, their altitude ranges from
5,000-6,000 feet in Mohmand and Malakand. The aspect of these hills is exceedingly dreary.
There are dry rivers between long rows of rocky hills and crags, scantily covered with
coarse grass, scrub wood, and dwarf palm.
The
mountains of Swat and Chitral includes three small ranges extending from the Hindukush to
the Kabul River. Three rivers flow through these ranges: the Swat or Chitral in the north,
the Kanhar in the south, and the Panjkora in the middle. The Lawarac Hills in Chitral
receive heavy snowfall in winter, when all routes to Chitral are blocked. The Lawarac Pass
is also situated in this range.
South
of the Kabul River, the strike of the ranges changes from north-south to west-east. The
west-east strike is strongly represented by the Koh-i-Safed Range. The general height of
this range is 3,600 meters the highest peak is Sakaram, rising to 4,761 meters. Outlying
mountains in Kohat District rise to 900 meters.
South
of the Koh-i-Safed are the Waziristan Hills. They are arid and extend to the banks of the
Gomal River. Three rivers, the Gomal, Kurram, and Tochi, flow through these hills. The
Suleiman Range begins to the south of the Gomal River and extends north-south. Its highest
peak is Takht-i-Suleiman, with height of 3,443 meters. At the southern end are the Bugti
and Marri Hills, draining westward to the Bolan River. These mountains are barren except
in the rainy season, when small brooks begin to flow. The most important river of this
region is the Bolan.
The
Kirthar Hills lie to the south of the Suleiman Range and along the western edge of the
Lower Indus Valley. These are low, dry hills. South of them flow the Hub and Lyari Rivers,
which fall into the Arabian sea near Karachi.
Passes
through the western bordering mountains are of special geographical and historical
interest. These include the Khyber, Kurram, Tochi, Gomal, and Bolan.
The Salt Range
The
Salt Range is the name given to two lines of low, rugged hills and the fertile land
between them. The Salt Range mountains are barren, but rich in minerals, containing coal,
gypsum, and one of the richest salt fields in the world. Its name comes from vast deposits
of rock salt which were left in its embrace by the receding sea. These salt deposits have
been mined in Khewra since ancient times.
The
Salt Range lies between the Indus and Jhelum Rivers in the Punjab. The range is
approximately 300 kilometers (186 miles) long from east to west, and its width in the
central and eastern parts is 5-19 miles. Starting near Jhelum District in the Jogi Tilla
and Bakrala ridges, the range crosses the Indus near Kalabagh. The average height of the
Salt Range is about 700 meters (2,200 feet). It rises to 1,522 meters (4,992 feet) near
Sakesar in Khushab District. The landscape in the Salt Range is varied. It contrasts
sharply with the Northern Areas. Stark masses of rock provide the first mountain barrier
between the plains of the subcontinent and Central Asia.
The
range consists of low mountains from which the top strata have been removed by erosion.
Forming the southern terrace of the Potohar Plateau 1,700 feet southwest of Rawalpindi,
the range consists of two asymmetrical parallel ridges divided by a longitudinal valley.
In the west and east, the range divides into separate mountain masses or massifs. West of
Sakesar, the course of the range swings to the northwest, with low, longitudinal ranges.
The Indus river breaks through at Kalabagh, flowing between vertical cliffs inaccessible
to communication.
The
summits of the Salt Range are slanting, hilly and plateau-like. The highest peaks are
Sakesar in the west and Chel (1,128 meters/3,700 feet) in the east. On the northern
slopes, a system of deep ravines has developed. There are small lakes of karstic
(sinkhole) origin without external drainage, including the beautiful salt lake, Kallar
Kahar. The water level of Lake Nammal is maintained by a dam. The Nammel River disappears
into the Indus alluvial plain before reaching the river. In the east, only the Bhwes River
has a constant flow into the Jhelum River.
The
Salt Range is said to record 600 million years of earth's history, with thick deposits
from Precambrian, Paleozoic, and Mesozoic times. On the southern slopes of the Salt Range,
in Khewra, Warcha, and Kalabagh, there are large deposits of rock salt. Smaller salt
deposits also occur in Jatta, Bahadur Khel, and Kharak. Coal deposits are found at Dandot,
Pidh, and Makarwal Kheji. Traces of petroleum are associated with limestone and sandstone
deposits in the western part of the Salt Range, and in the eastern part, layers of
bituminous shale, dolomite, and bauxite are found. Large deposits of high-grade gypsum and
anhydride also occur. Economically, salt, coal, and limestone mining are the most
important.
The
use of land for agriculture is limited because of a lack of water for irrigation. Small
valleys are terraced for cultivation of irrigated crops, using the water of lakes and
springs. In the valleys, dry farming prevails. To the southeast, a small, deciduous forest
with acacia, pine, and wild olive trees has been preserved by conservation.
The
only population centre of any size associated with the Salt Range is Jhelum. Most of the
towns in the range serve the mines and quarries. The main ethnic groups of the region are
the Pandzhabt, Pzhat and Arain people, who speak Indian languages (mainly Lakhrda). While
there is marginal farming in the valleys and on the few terraces, and some animal
husbandry on the overgrazed hill tracts, the principal occupation is salt mining.
As
it lies on the ancient route to the Punjab plains, the Salt Range is steeped in history.
Successive waves of adventurers and conquerors have left behind legends of their visits. |

PASSES
Bolan Pass
The
Bolan Pass has for centuries been the route traversed by traders, invaders, and nomadic
hordes travelling between the Indo-Pakistan subcontinent and Central Asia. At the mouth of
the Bolan Pass lies the city of Quetta. For many centuries this historic pass has served
as the main entrance to the Quetta District. It is historically significant as the gateway
used by most immigrants from Central Asia in their drive to discover new homelands in
South Asia.
The
pass extends from Kolpur, known to the natives as Kharlakai Kotal, to Rindli and is about
54 miles long. It is widest in the Laleji Plain on the south, narrowing to a gorge known
as Afghan Ponzak. The elevation rises from 750 to 5,900 feet.
The
Bolan area is bounded on the east by the Sarawan and Kachhi Divisions of the Kalat region
and is enclosed between high mountains belonging to the Central Brahui Range. The Bolan
River rises near Kolpur, but the water makes its first appearance at Sar-i-Bolan and
disappears again near Abigum. At Bibi Nani, it is joined from the west by the Sarawan
River, and from this point possesses a perennial stream. Many hill torrents empty into the
river, causing violent floods after a heavy rain.
In
1877, the Bolan Pass came under British control. Before this, it was under the control of
the Khan of Kalat, but the Kurd and Raisani tribes had acquired rights to levy transit
dues. The pass was also a favourite raiding ground of the Marri and Kakar tribes. In
pursuance of a policy of free trade between Kalat and India, posts were established in the
pass soon after the British occupation in 1877. Along with the Khyber Pass leading to
Kabul, the Bolan Pass was one of the two important "Gates of India." Proposals
to construct railways through these passes were advanced in 1857, but there was no system
of strategic railways until 1878. On the Bolan side, the nearest railway connection with
Afghanistan was in Sukkur until a line to Quetta was opened in August 1886. In 1887, a
broad gauge line was opened between Quetta and Bostan. In addition to the railway line, a
metalled road traverses the pass, connecting Sibi and Quetta.
In
the vicinity of the Bolan Pass there are only two villages of any size: Mach and Kirta.
The Kuchiks, a section of the Rind Baloch, are the cultivating proprietors of the soil.
The total area of cultivated land is 3,300 acres, about one-third of which is generally
cropped each year. Most of the cultivation is in Kirta, which is irrigated from the
permanent stream of the Bolan. The water and land are divided for each crop according to
the number of adult males among the Kuchiks. The principal crop is wheat. Some barley is
also cultivated in the summer. On the surrounding hills
grow pistachio trees and a few olive trees.
Thin
seams of coal in the Ghazij strata near Old Mach are worked by some private firms. Good
sulphur has also been discovered. However, no trade of importance exists, although Mach is
a coal loading railway station. Mach is also known for its jail, which is situated near
the station. All traffic to and from Quetta passes through the Bolan Pass, which thus
serves as the lifeline for Baloochistan's socioeconomic development.
Karakar Pass
The
Karakar Pass is situated at a height of 1,336 metres (4,384 feet) above sea level. From
the top of the pass, one can view Buner Valley. It was at this pass that the Emperor Akbar
lost most of his 8,000-man army in an abortive attempt to invade Swat in 1586. From the
top of the pass down to Barikot, the road runs through the pine forest.
Khunjerab Pass
Khunjerab
Pass, at 4,733 meters (15,528 feet), is the highest border crossing on a paved road in the
world. It connects Pakistan with China. A red sign announces, "China: drive
right," and a green sign says "Pakistan: drive left." A monument records
that the pass is 4,877 meters (16,000 feet) above sea and was opened in 1982. Khunjerab
Pass is on the continental watershed: water on the Pakistani side flows down to the Indian
Ocean, while that on the Chinese side is swallowed up
by the Taklamakan Desert in the Tarim Basin. The name Taklamakan literally means, "If
you go in, you don't come out."
The
scenery is remarkably different on either side of the pass. On the Pakistani side are
barren, deserted gorges with no sign of human life for the last 40 kilometers (25 miles)
before the border. The Chinese side is a wide, open, grassy, high-altitude plateau with
herds of yaks, sheep, and goats tended by Tajik herders, who live in yurts.
Khyber Pass
Khyber
is a Hebrew word meaning "fort." Paradoxical as it seems, Khyber, because of its
unique geography, looks like a citadel. Situated in the Suleiman Range, the Khyber Pass
connects Peshawar with Kabul. It is 55 kilometers in length.
The
Khyber, known in history as a corridor of invasions and the main trade route between
Central and South Asia, is one of the most important passes in the world. For both
historic and strategic reasons it has served as a gateway to the subcontinent. The Khyber
Pass has seen countless invasions. The Aryan, Persian, and Greek armies came through the
Khyber Pass, bringing such conquerors as Alexander the Great, Genghis Khan, Mahmud of
Ghazni, Timur, Babar, Nadir Shah, and Ahmed Shah Abdali. In the 19th century, the British
feared a Russian invasion of the subcontinent through the Khyber Pass.
The
Khyber Pass has been a silent witness to countless great events in the history of mankind.
The Aryan descending upon the fertile Indus Plains in 1500 BC, subjugating the indigenous
Dravadian population and settling there to open a glorious chapter in history of
civilization. The Persian hordes under Darius (6th century BC) crossed into the Punjab to
annex yet another province to the Archaemenian Empire. Alexander crossed the pass in 326
BC, to be followed by the Scythians, the Parthians, the Mughals, and the Afghans. The Turk
armies of the ruler of Ghazna Subaktagin, first crossed it in 997 AD. Later, his son,
Mahmud of Ghazna, marched through it seventeen times between 1001 and 1030 to attack
India. Shahabuddin Muhammad Ghauri crossed the Khyber Pass in 1175 to consolidate the
gains of the Muslims in India. He used the Khyber Pass again in 1193 to match his strength
against that of Pirthvi Raj Chouhan on the battlefield at Tarain.
In
1398, Amir Timur, the firebrand from Central Asia, invaded India through the Khyber Pass,
and his descendant, Zahiruddin Babur, made use of it first in 1505 and then in 1526 to
establish the mighty Mughal Empire. The Afghan King Ahmad Shah Abdali crossed the Khyber
Pass in 1761 and crushed the Maratha confederacy on the fields of Panipat. The Khyber
Valley saw a great deal of fighting between 1839 and 1919. The British used the Khyber
Pass during three Afghan wars in 1839, 1878, and 1919.
The
chapter of fighting in the Khyber, however, came to close with the independence of
Pakistan in 1947. The invasion of the Khyber Pass is still on, not by conquerors but by
tourists. Due to the war in Afghanistan, certain restrictions were imposed in 1979, but
they have since been removed.
The
Khyber Pass begins 11 miles west of Peshawar, some 3 miles from Jamrud, and stretches up
to the Pakistan-Afghan border at Torkham, 35 miles from Peshawar. Starting from the
foothills of the Suleiman Range, it gradually rises to an elevation of 3,000 feet above
sea level. The elevation of the hills of the pass reaches 3,373 feet at Landi Kotal, an
old caravanserai which is now a big trading centre of Khyber Agency.
From
a geographical point of view, the pass is one of nature's masterpieces. The narrow, steep
ascent to Ali Masjid, a village and at the summit of the pass some 10-1/2 miles from
Jamrud, is its most difficult part. The pass enters Afghan territory in Torkham, about 6
miles beyond Landi Kotal. The marketplace of Landi Kotal, 29 miles from Peshawar, is a
favorite tourist haunt. There are three roads in the Khyber Pass: a metalled road with
many bends and curves, a mule track known as the Caravan Route, and the railway extension,
completed in 1925-26. The railway line, threading its way through 34 tunnels and over 90
culverts and bridges, is a remarkable feat of engineering. The aggregate length of the
tunnels is about 3 miles. The railway line terminates at Landi Khana, 32 miles from
Peshawar, and the metalled black-top road, running parallel to the ancient caravan route,
continues up to Torkham. Passenger and cargo vehicles ply freely on this road without
armed escorts, a possibility unthinkable before the establishment of Pakistan.
Malakand Pass
The
Malakand Pass begins at Dargai. The road across the pass is in good condition, but is
always crowded with a continuous stream of trucks. From a viewpoint about one kilometer
before the top of the pass, one can see the Swat Canal in the valley below. It was built
by the British to channel water from the Swat River through a tunnel under the Malakand
Pass to the plains around Mardan.
On
the left, Malakand Fort guards the road at the top of the pass. On the other side of the
pass, the road descends through the market town of Bat Khela, with a Hindu Shahi fort
perched above it, and continues past the headworks of the Swat Canal to the Swat River.
The first bridge across the river is at Chakdara, which carries the road to Dir and
Chitral.
Margalla Pass
The
Margalla Pass is 28 kilometers from Islamabad. It has enjoyed a historical importance
quite out of proportion to its size, for it is little more than a gentle climb to a
cutting through a low line of hills. It could never have presented a serious obstacle to
any invader.
The
Margalla pass was the ancient and traditional route from the west and northwest through
the hills. Immediately beyond the present-day road cutting, up on the left, is a short
section of the precursor of the Grand Trunk Road, the Shahi (Imperial) Road, probably
built in the early 16th century by Sher Shah Suri, the great Afghan ruler who deposed
Babar's son Humayun for a short while, and who built Rohtas Fort. The road was engineered,
for its cobbles are still intact today.
The
first Moghal emperor Babar certainly used the Margalla Pass on his raids and invasions of
the subcontinent. In his memoirs, he calls it the Sangjaki Pass, after a nearly village.
The later Moghuls also used it on their way to Kashmir in the spring, when shorter routes
over the Pir Panjal mountains were blocked by snow. Jehangir wrote in his memoirs that the
name Margalla meant a place to plunder caravans.
Shandur Pass
Shandhur
Pass, at a height of 3,118 meters (10,230 feet) above sea level, is situated between the
Karakoram and the Hindukush Ranges. It connects Gilgit with Chitral. From the top, one can
see lower Chitral, with rows of barren mountains, and in the distance, the snow-clad
Hindukush. The descent is steep and winding, dropping 2,000 metres (7,000 feet) from the
top of the pass down to the river.
The
world's most exciting polo tournament is played on top of the Shandur Pass. The world's
highest polo ground is a place quite unique in itself, surrounded by some of the most
spectacular mountains in the world. The first polo tournament took place at Shandur Top in
1936, and by 1989, eight polo tournaments had been played there. Since 1989 the polo
tournament has become an annual event held from July 4-7.
Beside these
important Passes there are a few more which are listed below;
Babusar Pass: Babusar
Pass is situated at a height of 14,931 feet. It connects Abbottabad and Gilgit.
Baroghil Pass: Baroghil
Pass, situated at a height of 12, 480 feet connects Chitral with Wakhan (Afghanistan).

PLAINS
About
40 per cent of the land in Pakistan is made up of plains created by sediment brought in by
the Indus River and its tributaries. The Indus Plain can be divided into two parts: the
Upper and Lower Indus Plains.
Upper
Indus Plain
The
Upper Indus Plain extends from Attock to Mithankot, the junction of the Indus River with
its eastern tributaries. It includes most parts of the province of Punjab. Its elevation
ranges between 180 and 300 meters, with the northeastern part being comparatively higher.
Most of the plain consists of alluvial soil brought in by the rivers, but near Sargodha,
Chiniot, and Sangla, some old, dry hills appear above the plain. These are known as the
Kirana Hills.
Five
large rivers of the Punjab drain this plain. The land lying between two rivers is known as
a "doab." Thus the Upper Plain can be divided into four doabs, plus the
Bahawalpur and Derajat Plains. The Bari Doab
lies between the Beas and Ravi Rivers, the Rachna
Doab between the Ravi and the Chenab, the Chaj
Doab between the Chenab and the Jhelum, and the Sind Sagar Doab between the Indus and the Jhelum.
The
Bahawalpur Plain is grouped among the doabs, because the riverine tract, known locally as
Sind, is followed by an upland identical with the bars of the doabs. The northeastern part
is a cover and flood plain, the central part is a sand hill plain which has been largely
levelled and irrigated, and the southwestern portion is the cover flood plain of Dera
Nawab. This area is a reclaimed part of the Thar Desert. Along its southern border is the
Ghaggar Channelway, a depression three miles in width.
The
Derajat Plain is seamed with numerous stream and torrents, as is the Himalayan Piedmont on
the northern border of the Indus Plain. The land here varies between flat and gently
undulating, and the rivers have a comparatively steep gradient. The riverine tract, known
locally as Sindhu, is narrow.
Lower Indus Plain
Mithankot
is known as the junction of the Indus River with its eastern tributaries. Beyond
Mithankot, the Indus flows alone and carries not only its own water, but also that of its
eastern and western tributaries. While flowing through the province of Sindh, it becomes
several kilometers wide, especially during the flood season.
The
Indus flows very slowly, depositing most of its silt on its bed, which raises it above the
level of the sandy plain. The land on either side is protected by the embankments or
bunds. These are sometimes breached during the flood season.
The
Lower Indus Plain is structurally different from the Upper Indus Plain. The Lower Indus
Plain has been formed by the changing course of a single great river, and its deposits are
of a comparatively recent origin. The Lower Indus Plain, situated between the left bank of
the Indus River and the Thar Desert, is a level alluvial plain. It is fertile, but
rainfall is scanty, and agricultural activities cannot be carried out without irrigation.
Areas situated on the western side of the Indus are comparatively less fertile, while
areas lying to the northwest suffer from waterlogging and salinity.
The
Deltaic Plain
The
Indus Delta begins near Thatta (Sindh), where the Indus distributes itself into a number
of branches and finally joins with the waters of the Arabian Sea. The tidal deltaic area
covers an area between 36 to 45 square kilometers. Submerged during high tides, it
supports mangrove swamps. The old deltaic lands in the south are being reclaimed by the
canals of the Ghulam Muhammad Barrage, but most of the delta is a barren wasteland.
Kachhi-Sibi Plain
The
Kachhi-Sibi Plain is bounded on the north by the Marri-Bugti Range and on the west by the
Kalat Range. Surrounded on three sides by arid mountains, it is a barren, desolate area in
which heat, aridity, and uniformly textured soils create ideal conditions for mirages.
Sindh Plain
The
Sindh Plain forms the major part of the Lower Indus Plain. The Upper Sindh Plain is
agriculturally less developed, and more waterlogged and saline, than areas further south.
Lake Manchhar is alternately full or dry, according to the level of the Indus. The central
part of the plain has a uniform landscape, but one outstanding feature is the Rohri
Cuesta, a ridge of nummulitic limestone, attaining a height of 80 meters and extending 48
kilometers south from Sukkur.
The
Lower Sindh Plain, which starts from Hyderabad, is predominantly a cover flood plain. The
Ganjo Takkar Ridge, a cuesta of Kirthar limestone and an outlier of the Kohistan Ranges,
stretches southward from Hyderabad for a distance of about 24 kilometers. |

PLATEAUS
Balochistan Plateau
The
vast plateau of Balochistan lies west of the Suleiman and Kirthar Ranges. Its height
varies between 600 and 900 meters. Barren hills run across the plateau from northeast to
southwest. The Toba Kakar and Chagai Ranges in the north separate the Balochistan Plateau
from Afghanistan. The Ziarat and Muslim Bagh peaks rise to a height of 2,500 meters. In
the centre of the plateau lie the central Brahui and North Makran Hills, while in the
south is the Makran Range.
Most
of the northwestern part of the plateau is a desert. The salt water lake Hamun Mashkhel is
situated here. There is no big river in this part of the plateau, and there is very little
rainfall. The rivers of coastal Makran, the Porali, Hingol, and Dasht, flow into the
Arabian Sea. The rivers flow from the Suleiman Range
and falls into the Arabian Sea.
Valuable
minerals like coal, iron, chromite, copper, and natural gas have been found in many parts
of this region.
Potohar Plateau
The
Potohar Plateau has an area of 12,944 square kilometers, with an elevation of 300-600
meters. It is bounded on the east by the Jhelum River, on the west by the Indus River, on
the north by the Kala Chitta Range and the Margalla Hills, and on the south by the Salt
Range.
The
plateau slopes from northeast to southwest and, with the exception of the southeastern
portion, which drains into the Jhelum, belongs to the Soan Basin. Above the surface of the
Soan Basin rise the limestone and sandstone hills of Khairi, Murat, Kheir Mar, and Kala
Chitta. The Potohar Plateau is Pakistan's earliest proven oil-bearing region and has the
country's first and oldest oil refinery, located in Rawalpindi (Morgah).
The
plateau is drained by the Haro and Soan Rivers. Its topography is extremely varied,
consisting of ridges, troughs, and basins. A large part of the plateau has been eroded and
dissected by streams. |

RIVERS
Pakistan
possesses a number of rivers which are tributaries to the Indus. Five main rivers joining
its eastern side are the Jhelum, Chenab, Ravi, Beas, and Sutlej, besides three minor
rivers, the Soan, Haro, and Siran, which drain certain sub-mountainous areas. A number of
comparatively small rivers join the Indus on the west side. The biggest is the Kabul, with
its main tributaries, the Swat, Punj Kora, and Kunar. The Kurram, Gomal, Kohat Tai, Tank,
and several other small streams also join the Indus on the right side. All the main rivers
of Pakistan originate from the rainfall and snow-melt in the northern mountains.
To
solve the water dispute between India and Pakistan, the Indus Basin Water Treaty was
signed in 1960. According to that treaty, the three eastern rivers (the Ravi, Beas, and
Sutlej) were given to India, while the western rivers (the Indus, Jhelum, and Chenab) were
awarded to Pakistan.
Beas River
The
Beas is now the shortest of Punjab's rivers. Only 247 miles long, it joined the Sutlej
near Hariko in the 18th century. Originally, it joined the Chenab at Panjnad. The rim
station for this river is at Mandiplan near Talwara, district Hoshiarpur.
Two
dams have been built over the Beas, the Pandoh and Pong Dams. The Ravi-Beas link carries
the water of the Madhopur. After completion of the Thein Dam in the entire waters of the
Ravi will be stored and used in India.
Chenab River
The
Chenab River originates in Kulu and Kangra districts of Himachel Pardesh (India). The two
chief streams of the Chenab, the Chandra and Bhaga, rise on opposite sides of Baralcha
Pass at an elevation of about 16,000 feet. These join at Tandi in Jammu and Kashmir,
nearly 9,090 feet above mean sea level.
