Himalayas - the legendary majestic beauty.

Dear reader,

welcome to the adventure world.

This edition provides you an introduction to Himalayas.

Himalayan Mountain Range
Ranges: Main Himalayan Range, Pir Panjal Range, Dhaula Dhar Range, Siwalik Hills, Zanskar Range, Ladakh Range, & East Korakoram Range
The Himalayas is one of the youngest mountain ranges in the world. Its revolution can be traced to the Jurassic Era (80 million years ago) when the world’s landmasses were split into two: Laurasia in the Northern hemisphere, and Gondwanaland in the southern hemisphere. The landmass which is now India broke away from Gondwanaland and floated across the earth’s surface until it collided with asia. The hard volcanic rocks of India were thrust against the soft sedimentary crust of Asia, creating the highest mountain range in the world.

The River System
It was a collision that formed mountain ranges right across asia, including the karakoram, the pamirs, the Hindukush, the Tien Shan and the Kun Lun. The Himalayan Mountains, at the front of this continental collision, are still being formed, rising and assuming complex profiles. For the ancient geographer, the complexities of this vast mountain range were a constant source of speculation. From the earliest accounts, Mt. Kailash was believed to be the centre of the universe with the River systems of the Indus, the Brahmaputra, and the Sutlej all flowing from its snowy ridges and maintaining the courses which they had followed prior to the forming of the Himalaya.The Sutlej was able to maintain its course flowing directly from Tibet through the main Himalaya range to the Indian subcontinent, while the huge gorges on both flanks of the Himalaya reflect the ability of the Indus and the Brahmaputra to follow their original courses. The Indus flows west until it rounds the Himalaya by the Nanga Parbat Massif, while the Brahmaputra flows eastwards for nearly 1000-kms around the Assam Himalayas and descends to the Bay of Bengal. It was not surprising, therefore, that 19th century geographers experienced formidable difficulties n tracing the River systems, and defining the various mountain ranges that constitute the Himalaya. Even today, with the advent of satellite pictures and state-of-the-art ordnace maps, it is still difficult to appreciate the form and extent of some of the ranges that constitute the Himalaya.

Main Himalaya Range
This is the principal mountain range dividing the Indian subcontinent from Nanga Parbat in the west, the range stretches for over 2,000-km to the mountains bordering Sikkim and Bhutan in the east. The west Himalaya is the part of this range that divides Kashmir and Himachal Pradesh from Ladakh. The highest mountains here are Nun and Kun. In Kashmir the subsidiary ridges of the Himalaya include the North Sonarmarg, Kolahoi and Amarnath ranges. Further east, the Himalaya extends across to the Baralacha range in Himachal Pradesh before merging with the Parbati range to the east of the Kullu valley. It then extends across kinnaur Kailas to the swargarohini and Bandarpunch ranges in Uttaranchal. Further east it is defined by the snow capped range North of the Gangotri glacier and by the huge peaks in the vicinity of Nanda Devi, the highest mountain in the Indian Himalaya. In Western Nepal the range is equally prominent across the Annapurna and Dhaulagiri massifs, while in Eastern Nepal the main ridgeline frequently coincides with the political boundary between Nepal and Tibet.

Major Passes
The major passes over the main Himalaya range include the Zoji la, at the head of the Sindh valley; the Boktol pass, at the head of the Warvan valley; the Umasi la in the Kishtwar region; and Thekang la and the Shingo la between Lahaul and the Zanskar region of Ladakh. It also includes the Pin Parbati pass between Lahaul and the Zanskar region of Ladakh. It also includes the Pin Parbati pass between the Kullu valley and Spiti, while in Kinnaur it is traversed when crossing the charang la in the Kinnaur Kailash range.In Uttaranchal, roads are being constructed to the main places of pilgrimage in the heart of the Himalaya. These include Yamunotri and the source of the Yamuna River, Gangotri at the head of the Bhagirathi valley, Kedarnath at the head of the Mandakini valley, and Badrinath in the Alaknanda valley. There are, however, many trekking possibilities across the mountain ridges and glacial valleys including tose bordering the Nanda Devi sanctuary.The main Himalaya range extends east across central Sikkim from the huge Kangchenjunga massif, which includes Kangchenjunga I, the world’s third highest peak. The east Himalaya is breached by the headwaters of the Tista River, which forms the geographical divide between the verdant alpine valleys to the south and the more arid regions that extend North to Tibet. Trekking possibilities are at present confined to the vicinity of the Singali ridge, an impressive range that exxtends south from the main Himalaya and forms the border between India and Nepal.In Darjeeling the treks include the route along the southern extremity of the Singali range, while in Sikkim the trails out of Yuksom explore the ridges and valleys to the south to the Kangchenjunga massif.

Pir Panjal Range

The Pir Panjal Range lies south of the main Himalaya at an average elevation of 5,000m. From Gulmarg in the North west it follows the southern rim of the Kashmir valley to the Banihal pass. Here the Pir Panjal meets the ridgeline separating the Kashmir valley from the Warvan valley. From Banihal the Pir Panjal sweeps south-east to Kishtwar, where the combined waters of the Warvan and Chandra Rivers meet to form the Chenab River, one of the main tributaries of the Indus.Passes In Pir PanjalThe main passes over the Pir Panjal include the pir panjal pass due west of Srinagar, the Banihal pass which lies at the head of the Jhelum River at the southern end of the Kashmir valley, and the sythen pass linking Kashmir with Kishtwar. In Himachal Pradesh the main passes are the Sach which links the Ravi and the Chandra valleys, and the Rohtang, which links the Beas and Kullu valleys with the upper Chandra valley and Lahaul. Roads are constructed over all these passes. The Banihal is now tunnelled and another road has been made over the Sythen pass in Kashmir and the Sach pass in Himachal Pradesh. For trekkers there is still the attraction of the Kugti, Kalicho and Chobia passes between the Ravi valley and Lahaul, and the Hampta pass links the Kullu valley with Lahaul.

Dhaula Dhar Range
The Dhaula Dhar range lies to the south of the Pir Panjal. It is easily recognised as the snow-capped ridge behind Dharamsala where it forms the divide between the Ravi and the Beas valleys. To the west it provides the divide between the Chenab valley below Kishtwar and the Tawi valley which twists south to Jammu. This is the range crossed at Patnitop on the Jammu-Srinagar highway. To the east it extends across Himachal Pradesh forming the high ridges of the Largi gorge and extending south of the Pin Parvati valley before forming the impressive ridgeline east of the Sutlej River. Thereon it forms the snow capped divide between the Sangla valley and upper tons catchment area in Uttaranchal, including the Har Ki Dun Valley. Beyond the Bhagirathi River it forms the range between Gangotri and Kedarnath before merging with the main Himalaya at the head of the Gangotri glacier.There are many attractive trekking pases over the Dhaula Dhar. These include the Indrahar Pass North of Dharamsala: and in Kinnaur, the Borasu pass linking the Sangla valley to Har-ki-Dun in Uttaranchal.

Siwalik Hills
The Siwalik Hills, also known as Shiwalik Hills, lie to the south of the Dhaula Dhar, with an average elevation of 1,500 to 2,000m. They are the first range of hills encountered en route from the plains and are geologically separate from the Himalaya. They include the Jammu hills and Vaishno Devi, and extend to Kangra and further east to the range south of Mandi. In Uttaranchal , they extend from Dehra Dun to Almora before heading across the southern borders of Nepal. Most of the range is crossed by a network of roads, linking the Northern Indian plains with Kangra, the Kullu valley, Shimla and Dehradun.

Zanskar Range
The Zanskar range lies to the North of the main Himalaya. It forms the backbone of Ladakh south of the Indus River, stretching from the ridges beyond Lamayuru in the west across the Zanskar region, where it is divided from the main Himalaya by the Stod and Tsarap valleys, the populated districts of the Zanskar valley. The Zanskar range is breached where the Zanskar River flows North, creating awesome gorges until it reaches the Indus River just below Leh. To the east of the Zanskar region the range continues through Lahaul & Spiti, providing a complex buffer zone between the main Himalaya and the Tibetan plateau. It continues across the North of Kinnaur before extending west across Uttaranchal, where it again forms the intermediary range between the Himalaya and the Tibetan plateau, which includes Kamet, the second highest peak in India. The range finally peters out North east of the Kali River - close to the border between India and Nepal.On the Zanskar range, the Fatu La, on the Leh-Srinagar road, is considered the most easterly pass; while the Singge La, the Cha Cha La and the Rubrang La are the main trekking passes into the Zanskar valley. For the hardy Ladakh trader, the main route in winter between the Zanskar valley and Leh is down the icebound Zanskar River gorges. Further to the east, many of the Zanskar range passes to the North of Spiti and Kinnaur are close to the India-Tibet border, and are closed to Trekkers

Ladakh Range
The ladakh range lies to the North of Leh and is an integral part of the Trans-Himalayan range that merges with the Kailash range in Tibet. The passes include the famous Kardung La, the highest motorable pass in the world, while the Digar La to the North east of Leh is at present the only pass open to trekkers..

East Korakoram Range
The East Karakoram Range is the huge range that forms the geographical divide between India and Central Asia. It includes many high peaks including - Teram Kargri, Saltoro Kangri and Rimo, while the Karakoram Pass was the main trading link between the markets of Leh, Yarkand and Kashgar. At present this region is closed to trekkers, although a few foreign mountaineering groups were permitted to climb there in the last decade.
