The Siachen Glacier is located in the eastern Karakoram range in the Himalaya Mountains 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 China border down to 3,620 m (11,875 ft) at its terminus. The entire Siachen Glacier, with all major passes, is currently under the administration of India since 1984, while Pakistan controls the region west of Saltoro Ridge with Pakistani posts located 3,000 ft below 100 Indian posts on Saltoro Ridge.
The Siachen conflict, sometimes referred to as the Siachen War, is a military conflict between India and Pakistan over the disputed Siachen Glacier region in Kashmir. A cease-fire went into effect in 2003. The conflict began in 1984 with India's successful Operation Meghdoot during which it gained control over all of the Siachen Glacier. Following the UN-mediated ceasefire in the 1949, the line between India and Pakistan was demarcated up to point NJ9842 at the foot of the Siachen Glacier.
