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 as part of the union territory of Ladakh, located in the Kashmir region 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 1 km below more than 100 Indian posts on the ridge.
K12 is the second highest peak in the Saltoro Mountains, a subrange of the Karakoram range in the Siachen region and is administered as a part of Ladakh territory. Its name comes from its designation given during the original survey of the Karakoram range. In 1984, an Indian army expedition under Colonel Prem Chand took hold of this peak, from the side of Siachen glacier by traversing from the west.
The Karachi Agreement of 1949 was signed by the military representatives of India and Pakistan, supervised by the United Nations Commission for India and Pakistan, establishing a cease-fire line in Kashmir following the Indo-Pakistani War of 1947. It established a cease-fire line which has been monitored by United Nations observers from the United Nations since then.
The Trans-Karakoram Tract, also known as the Shaksgam Tract, is an area of approximately 5,200 km2 (2,000 sq mi) north of the Karakoram watershed, including the Shaksgam valley. The tract is administered by China as part of its Taxkorgan and Yecheng counties in the Xinjiang Uyghur Autonomous Region. Although the Shaksgam tract was originally under the control of India following the accession of Jammu and Kashmir to India in 1947, Pakistan took control of the region after the First India-Pakistan War and subsequently ceded it to China in 1963 through the Sino-Pakistan Agreement, and a border based on actual ground positions was recognized as the international border by China and Pakistan. The Shaksgam Tract, along with the entire Kashmir region, is claimed by India. Further, New Delhi has never accepted the China-Pakistan boundary pact, asserting that Islamabad "unlawfully" attempted to cede the area to Beijing.
Astore District is a district of Pakistan-administered Gilgit-Baltistan in the disputed Kashmir region. It is one of the 14 districts of the Pakistani-administered territory of Gilgit−Baltistan. Its administrative headquarters are located at Eidgah in the Astore Valley. Astore District is bounded by Gilgit District to the north, Roundu District to the northeast, Skardu District to the east, Kharmang District to the southeast, Diamer District to the west, the Neelum District of Azad Jammu and Kashmir to the southwest, and the Bandipore District of Indian-administered disputed Kashmir region to the south.
Operation Meghdoot was the codename for the Indian Army operation to take full control of the Siachen Glacier in Ladakh. Executed on the morning of 13 April 1984 in the highest battlefield in the world, Meghdoot was the first military offensive of its kind. This operation preempted Pakistan's Operation Ababeel and was a success, resulting in Indian forces gaining control of the Siachen Glacier in its entirety.
The Saltoro Mountains form a subrange within the Karakoram Range and are situated in the southeastern part of the Karakoram. They lie on the southwest side of the Siachen Glacier, which is one of the two longest glaciers in the world outside the polar regions. The name "Saltoro" is also associated with the Saltoro Valley, located west of this range and descending on the Pakistani side of the Saltoro Range, which generally follows the Actual Ground Position Line (AGPL).
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.
Ghent Kangri is a high peak near the north end of the Saltoro Mountains, a subrange of the Karakoram range. It is located west of the Siachen Glacier near the Actual Ground Position Line between India and Pakistan.
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 have characterized it as pointless, given the perceived uselessness of the territory, and indicative of bitter stubbornness on both sides.
Bilafond La (meaning "Pass of the Butterflies" in Balti language, also known as the Saltoro Pass, is a mountain pass situated on Saltoro Ridge, sitting immediately west of the vast Siachen Glacier, some 40 km directly north of map point NJ 980420 which defined the end of the 1972 Line of Control between Pakistan and India as part of the Simla Agreement. Bilafond La is on the ancient Silk Route linking the Indian Subcontinent and China.
Sia La is a mountain pass situated on Saltoro Ridge, in Gilgit Baltistan, Pakistan 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 Nubra River is a river in the Nubra Valley of Ladakh in India. It is a tributary of the Shyok River and originates from the Siachen Glacier, the second-longest non-polar glacier in the world. In earlier Tibetan maps, it was referred to as Yarma Tsangpo.
Gyong La is a mountain pass situated on Saltoro Ridge southwest of the vast Siachen Glacier, some 20 km (12 mi) directly north of map point NJ9842 which defined the end of the 1972 Line of Control between India and Pakistan. With Pakistan controlling areas just to the west along Chumik Glacier, the immediate Gyong La area has been under India's control since 1989. Dozens of Indian military tents and other equipment are visible in 2013 and 2016 Google Earth imagery 100 meters east, 670 meters northeast, and 2.7 km east-northeast of Gyong La, linked by clear trails. Nearer the former Pakistani "Naveed Top" position and 3.85 km west-northwest of Gyong La is a post and helipad is visible in 2001 and 2016 Google Earth imagery at 5,800 m (19,000 ft) elevation, higher than both the Indian positions and Gyong La.
The Actual Ground Position Line (AGPL) divides current positions of Indian and Pakistani military posts and troops along the entire 110 kilometres (68 mi) long frontline 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 (2.5 mi) northwest of Indira Col West, with peaks in excess of 7,000 m (23,000 ft) and temperatures ranging to around −55 °C (−67 °F). 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 Karakoram Mountains, one of the world's tallest mountain ranges. Hunza District,.
