Siachen Glacier

The Siachen Glacier is a glacier located in the eastern Karakoram range of the Himalayas, just northeast of the point NJ9842 where the Line of Control between India and Pakistan ends in the disputed Kashmir region. 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 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. The Siachen Glacier lies immediately south of the great drainage divide that separates the Eurasian Plate from the Indian subcontinent in the extensively glaciated portion of the Karakoram sometimes called the "Third Pole". The glacier lies between the Saltoro Ridge immediately to the west and the main Karakoram range to the east. The Saltoro Ridge originates in the north from the Sia Kangri peak on the China border in the Karakoram range. The crest of the Saltoro Ridge's altitudes range from 5,450 to 7,720 m (17, 880 to 25, 330 feet).
