Ladakh shares border with Jammu and Kashmir
Ladakh () is a region administered by India as a union territory which constitutes a part of the larger Kashmir region and has been the subject of dispute between India, Pakistan, and China since 1947. Ladakh is bordered by the Tibet Autonomous Region to the east, the Indian state of Himachal Pradesh to the south, both the Indian-administered union territory of Jammu and Kashmir and the Pakistan-administered Gilgit-Baltistan to the west, and the southwest corner of Xinjiang across the Karakoram Pass in the far north. It extends from the Siachen Glacier in the Karakoram range to the north to the main Great Himalayas to the south. The eastern end, consisting of the uninhabited Aksai Chin plains, is claimed by the Indian Government as part of Ladakh, and has been under Chinese control since 1962.In the past, Ladakh gained importance from its strategic location at the crossroads of important trade routes, but as Chinese authorities closed the borders between Tibet Autonomous Region and Ladakh in the 1960s, international trade dwindled. Since 1974, the Government of India has successfully encouraged tourism in Ladakh. As Ladakh is strategically important, the Indian military maintains a strong presence in the region.
The largest town in Ladakh is Leh, followed by Kargil, each of which headquarters a district. The Leh district contains the Indus, Shyok and Nubra river valleys. The Kargil district contains the Suru, Dras and Zanskar river valleys. The main populated regions are the river valleys, but the mountain slopes also support pastoral Changpa nomads. The main religious groups in the region are Muslims (mainly Shia) (46%), Buddhists (mainly Tibetan Buddhists) (40%), and Hindus (12%) with the remaining 2% made of other religions. Ladakh is one of the most sparsely populated regions in India. Its culture and history are closely related to those of Tibet.Ladakh was established as a union territory of India on 31 October, 2019, following the passage of the Jammu and Kashmir Reorganisation Act. Prior to that, it was part of the Jammu and Kashmir state. Ladakh is both the largest and the second least populous union territory of India.Historically, the region included the Baltistan (Baltiyul) valleys (now mostly in Pakistani administered part of Kashmir), the entire upper Indus Valley, the remote Zanskar, Lahaul and Spiti to the south, much of Ngari including the Rudok region and Guge in the east, Aksai Chin in the northeast, and the Nubra Valley to the north over Khardong La in the Ladakh Range. Contemporary Ladakh borders Tibet to the east, the Lahaul and Spiti regions to the south, the Vale of Kashmir, Jammu and Baltiyul regions to the west, and the southwest corner of Xinjiang across the Karakoram Pass in the far north. The historic but imprecise divide between Ladakh and the Tibetan Plateau commences in the north in the intricate maze of ridges east of Rudok including Aling Kangri and Mavang Kangri, and continues southeastward toward northwestern Nepal. Before partition, Baltistan, now under Pakistani control, was a district in Ladakh. Skardu was the winter capital of Ladakh while Leh was the summer capital.
The mountain ranges in this region were formed over 45 million years by the folding of the Indian Plate into the more stationary Eurasian Plate. The drift continues, causing frequent earthquakes in the Himalayan region. The peaks in the Ladakh Range are at a medium altitude close to the Zoji-la (5,000–5,500 m or 16,400–18,000 ft) and increase toward southeast, culminating in the twin summits of Nun-Kun (7,000 m or 23,000 ft).
The Suru and Zanskar valleys form a great trough enclosed by the Himalayas and the Zanskar Range. Rangdum is the highest inhabited region in the Suru valley, after which the valley rises to 4,400 m (14,400 ft) at Pensi-la, the gateway to Zanskar. Kargil, the only town in the Suru valley, is the second most important town in Ladakh. It was an important staging post on the routes of the trade caravans before 1947, being more or less equidistant, at about 230 kilometres from Srinagar, Leh, Skardu and Padum. The Zangskar valley lies in the troughs of the Stod and the Lungnak rivers. The region experiences heavy snowfall; the Pensi-la is open only between June and mid-October. Dras and the Mushkoh Valley form the western extremity of Ladakh.
The Indus River is the backbone of Ladakh. Most major historical and current towns – Shey, Leh, Basgo and Tingmosgang (but not Kargil), are close to the Indus River. After the Indo-Pakistani War of 1947, the stretch of the Indus flowing through Ladakh became the only part of this river, which is greatly venerated in the Hindu religion and culture, that still flows through India.
The Siachen Glacier is in the eastern Karakoram Range in the Himalaya Mountains along the disputed India-Pakistan border. The Karakoram Range forms a great watershed that separates China from the Indian subcontinent and is sometimes called the "Third Pole." The glacier lies between the Saltoro Ridge immediately to the west and the main Karakoram Range to the east. At 76 km (47 mi) long, it is the longest glacier in the Karakoram and second-longest in the world's non-polar areas. It falls from an altitude of 5,753 m (18,875 ft) above sea level at its source at Indira Col on the China border down to 3,620 m (11,880 ft) at its snout. Saser Kangri is the highest peak in the Saser Muztagh, the easternmost subrange of the Karakoram Range in India, Saser Kangri I having an altitude of 7,672 m (25,171 ft).
The Ladakh Range has no major peaks; its average height is a little less than 6,000 m (20,000 ft), and few of its passes are less than 5,000 m (16,000 ft). The Pangong range runs parallel to the Ladakh Range for about 100 km (62 mi) northwest from Chushul along the southern shore of the Pangong Lake. Its highest point is about 6,700 m (22,000 ft) and the northern slopes are heavily glaciated. The region comprising the valley of the Shayok and Nubra rivers is known as Nubra. The Karakoram Range in Ladakh is not as mighty as in Baltistan. The massifs to the north and east of the Nubra–Siachen line include the Apsarasas Group (highest point at 7,245 m or 23,770 ft) the Rimo Muztagh (highest point at 7,385 m or 24,229 ft) and the Teram Kangri Group (highest point at 7,464 m or 24,488 ft) together with Mamostong Kangri (7,526 m or 24,692 ft) and Singhi Kangri (7,202 m or 23,629 ft). North of the Karakoram lies the Kunlun. Thus, between Leh and eastern Central Asia there is a triple barrier – the Ladakh Range, Karakoram Range, and Kunlun. Nevertheless, a major trade route was established between Leh and Yarkand.
