Kashmir is the northernmost geographical region of the Indian subcontinent. Until the mid-19th century, the term "Kashmir" denoted only the Kashmir Valley between the Great Himalayas and the Pir Panjal Range. Today, the term encompasses a larger area that includes the Indian-administered territories of Jammu and Kashmir and Ladakh, the Pakistani-administered territories of Azad Kashmir and Gilgit-Baltistan, and the Chinese-administered territories of Aksai Chin and the Trans-Karakoram Tract.
The Karakoram is a mountain range in Kashmir spanning the borders of Pakistan, China, and India, with the northwest extremity of the range extending to Afghanistan and Tajikistan. Most of Karakorum mountain range falls under jurisdiction of Gilgit-Baltistan which is controlled by Pakistan. Its highest peak, K2, is located in Gilgit-Baltistan. It begins in the Wakhan Corridor (Afghanistan) in the west, encompasses the majority of Gilgit-Baltistan, and extends into Ladakh and Aksai Chin. It is the second highest mountain range in the world and part of the complex of ranges including the Pamir Mountains, the Hindu Kush and the Himalayan Mountains. The Karakoram has eighteen summits over 7,500 m (24,600 ft) height, with four of them exceeding 8,000 m (26,000 ft): K2, the second highest peak in the world at 8,611 m (28,251 ft), Gasherbrum I, Broad Peak and Gasherbrum II.
The Siachen Glacier is a glacier located in the eastern Karakoram range in the Himalayas at about 35.421226°N 77.109540°E, just northeast of the point NJ9842 where the Line of Control between India and Pakistan ends. 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 head at Indira Col on the India–China border down to 3,620 m (11,875 ft) at its terminus. The entire Siachen Glacier, with all major passes, has been under the administration of India since 1984. Pakistan maintains a territorial claim over the Siachen Glacier and controls the region west of Saltoro Ridge, lying west of the glacier, with Pakistani posts located 3,000 ft below more than 100 Indian posts on the ridge.
The Trans-Karakoram Tract, also known as Shaksgam Tract, is an area of approximately 5,300 km2 (2,050 sq mi) north of the Karakoram watershed, including the Shaksgam valley and Raskam. The tract is administered by China as part of its Taxkorgan and Yecheng counties in the Xinjiang Uyghur Autonomous Region. Although Shaksgam tract was never under the control of Pakistan since 1947, During 1963 Sino-Pakistan Agreement, Pakistan recognized Chinese sovereignty over Shaksgam tract while China also recognized Pakistani sovereignty over Gilgit Agency and a border based on actual ground positions was recognized as international border by China and Pakistan. It is claimed by India as part of the Union territory of Ladakh.
The Karakoram Pass is a 5,540 m or 18,176 ft mountain pass between India and China in the Karakoram Range. It is the highest pass on the ancient caravan route between Leh in Ladakh and Yarkand in the Tarim Basin. 'Karakoram' literally means 'Black Gravel' in Mongolic.
Operation Meghdoot was the codename for the Indian Armed Forces' operation to seize control of the Siachen Glacier in Kashmir, precipitating the Siachen conflict. Executed in the morning of 13 April 1984 in the highest battlefield in the world, Meghdoot was the first military offensive of its kind. The operation preempted Pakistan's impending Operation Ababeel and was a success, resulting in Indian forces gaining control of the Siachen Glacier in its entirety.
The Saltoro Mountains are a subrange of the Karakoram Range. They are located in the southeast Karakoram on the southwest side of the Siachen Glacier, one of the two longest glaciers outside the polar regions. The name given to this range is shared with the Saltoro Valley which is located to the west of this range, downslope on the Pakistan side of the Saltoro Range which generally follows the Actual Ground Position Line. Saltoro Kangri peak, Saltoro River, and Saltoro Valley are features on this range. The Actual Ground Position Line (AGPL) between Indian and Pakistan held area runs through this range, where the high peaks and passes of the Siachen area are held by India, whereas Pakistan occupies the lower peaks and valleys to the west.
The Rimo Muztagh is one of the most remote subranges of the Karakoram range. The southern part of Rimo Muztagh is in the Ladakh portion of far northwestern India, also claimed by Pakistan. The northern half, including the Rimo massif, is in the Siachen area. It is far from major towns, and close to the militarily sensitive Siachen Glacier, so it has seen little exploration or climbing activity compared to, for example, the nearby Baltoro Muztagh. The highest peak is Mamostong Kangri, 7,516 metres.
Rimo I is the main summit of the Rimo massif with an elevation of 7,385 metres (24,229 ft).
The Teram Kangri group is a mountain massif in the remote Siachen Muztagh, a subrange of the Karakoram range. The high point of the group, and of the Siachen Muztagh, is Teram Kangri I. The peak lies on the boundary between disputed China controlled Trans-Karakoram Tract and the disputed Siachen Glacier controlled by India. The northeast side of the peak is in Chinese-controlled territory, the southwest side is controlled by India. Teram Kangri I was first climbed on August 10, 1975, by a Japanese expedition led by H. Katayama, which obtained a permit from the Govt. of Pakistan and made the long approach via Bilafond La. They climbed the SW ridge of Teram Kangri II and then took the East ridge to the top. Teram Kangri II was climbed on August 12 and 13 by six Japanese climbers.
Gilgit-Baltistan has been under Pakistan administration since 1947 and was given self-governing status on August 29, 2009. Gilgit-Baltistan comprises 10 districts within three divisions. The four districts of Skardu Kharmang Shigar and Ghanche are in the Baltistan Division, four districts of Gilgit Ghizer Hunza and Nagar districts which were carved out of Gilgit District are in the Gilgit Division and the third division is Diamir, comprising Chilas and Astore. The main political centres are the towns of Gilgit and Skardu.
The Shyok River a tributary of the Indus River that flows through northern Ladakh and enters Gilgit–Baltistan, spanning some 550 km (340 mi).
The Siachen conflict, sometimes referred to as the Siachen Glacier conflict or the Siachen War, was a military conflict between India and Pakistan over the disputed 1,000-square-mile (2,600 km2) Siachen Glacier region in Kashmir. The conflict was started in 1984 by India's successful capture of the Siachen Glacier as part of Operation Meghdoot, and continued with Operation Rajiv in 1987. India took control of the 70-kilometre-long (43 mi) Siachen Glacier and its tributary glaciers, as well as all the main passes and heights of the Saltoro Ridge immediately west of the glacier, including Sia La, Bilafond La, and Gyong La. Pakistan controls the glacial valleys immediately west of the Saltoro Ridge. A cease-fire went into effect in 2003, but both sides maintain a heavy military presence in the area. The conflict has resulted in thousands of deaths, mostly due to natural hazards. External commentators of have characterized it as pointless, given the perceived uselessness of the territory, and indicative of bitter stubbornness on both sides.
Sia La is a mountain pass situated on Saltoro Ridge, in Ladakh, India, some 60 km (37 mi) north-northwest of map point NJ9842 which defined the end of the 1972 Line of Control between India and Pakistan as part of the Simla Agreement. Sia La sits near the Chinese border and immediately northwest of the upper part of the vast Siachen Glacier, connecting that glacier to the Pakistani-controlled Kondus Glacier and valley to the west.
The Shaksgam River is a left tributary of the Yarkand River. The river is also known as the Kelechin River and Muztagh River. It rises in the Gasherbrum, Urdok, Staghar, Singhi and Kyagar Glaciers in the Karakoram. It then flows in a general northwestern direction parallel to the Karakoram ridge line in the Shaksgam Valley. It receives the waters of the Shimshal Braldu river and the Oprang river from the Pakistan-administered Hunza District before turning east and joining the Yarkand River. The stretch of the river's course between Shimshal Braldu and Oprang is used as the Pakistan–China border.
The Depsang Plains represent a high-altitude gravelly plain at the northwest portion of the disputed Aksai Chin region of Kashmir, divided into Indian and Chinese administered portions across a Line of Actual Control. India controls the western portion of the plains as part of Ladakh, whereas the eastern portion is controlled by China and claimed by India. The Line of Control with Pakistan-administered Gilgit-Baltistan is 80 kilometres (50 mi) west of the Depsang Plains with the Siachen Glacier in-between. Ladakh's traditional trade route to Central Asia passed through the Depsang Plains, with the Karakoram Pass lying directly to its north.
The Actual Ground Position Line (AGPL) divides current positions of Indian and Pakistani military posts and troops across the entire 110 kilometres (68 mi) long front line in the disputed region of Siachen Glacier. AGPL generally runs along the Saltoro Mountains range, beginning from the northernmost point of the (LOC) at Point NJ 9842 and ending in the north on the Indira Ridge at the India-China-Pakistan LAC tripoint near Sia Kangri about 4 km northwest of Indira Col West, with peaks in excess of 7,000 meters and temperatures ranging to around minus 55 Celsius. India gained control of 1,000 square miles (2,600 km2) of disputed territory in 1984 because of its military operations in Siachen. A cease-fire was announced in 2003.
NJ9842, also called NJ 980420, is the northernmost demarcated point of the India-Pakistan cease fire line in Kashmir known as the Line of Control (LoC). The India–Pakistan AGPL, begins from the NJ9842 on LoC and ends near the Indira Ridge at the trijunction of areas controlled by China, India, and Pakistan.
Indira Col West is a mountain pass at 5,988 metres (19,646 ft)) altitude on the Indira Ridge of Siachen Muztagh in Karakoram Range. It is on the border between Indian-controlled Siachen Glacier and the Chinese-controlled Trans-Karakoram Tract, close to the tripoint of India, Pakistan, and China. The India-Pakistan Actual Ground Position Line (AGPL) in the Siachen area ends near the pass. It is possible to ascend the pass from both the north and south sides controlled by China and India respectively.
The China–Pakistan border is 596 kilometres (370 mi) and runs west–east from the tripoint with Afghanistan to the disputed tripoint with India in the vicinity of the Siachen Glacier. It traverses the Karakorum Mountains, one of the world's tallest mountain ranges. Hunza District, Shigar District and Ghanche District in Gilgit-Baltistan administered by Pakistan border Taxkorgan Tajik Autonomous County and Kargilik/Yecheng County in Kashgar Prefecture, Xinjiang Uygur Autonomous Region, China.
