The Siachen Glacier is located in the eastern Karakoram range in the Himalaya Mountains at about 35°25′16″N 77°06′34″E / 35.421226°N 77.109540°E / 35.421226; 77.109540, just north of the Line of Control between India and Pakistan. At 70 km (43 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 Siachen Glacier lies immediately south of the great watershed 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). The major passes on this ridge are, from north to south, Sia La at 5,589 m (18,336 ft), Bilafond La at 5,450 m (17,880 ft), and Gyong La at 5,689 m (18,665 ft). The average winter snowfall is 10.5 m (35 ft) and temperatures can dip to −50 °C (−58 °F). Including all tributary glaciers, the Siachen Glacier system covers about 700 km² (270 sq mi).

Harish Kapadia (Born 11 July 1945) is a distinguished Himalayan Mountaineer from India. He has been awarded the Patron's Medal of the Royal Geographic Society, UK and the Life Time Achievement Award for Adventure by the President of India and the King Albert Mountain Award presented by The King Albert I Memorial Foundation. He has written numerous books and articles on the Indian Himalaya.

He began climbing and trekking in the range around Bombay, the Western Ghats. His first visit to the Himalaya was almost 40 years ago^[when?]. His main contribution to Himalayan climbing has been to explore unknown areas and, in number of cases, to open up climbing possibilities. Some of his major ascents have been of Devtoli (6788 m), Bandarpunch West (6102 m), Parilungbi (6166 m), in 1995, Lungser Kangri (6666 m) the highest peak of Rupshu in Ladakh. He led five international joint expeditions, four with the British and two with the French, to high peaks, such as Rimo I (7385 m), Chong Kumdan Kangri I (7071 m), Sudarshan Parbat, and the Panch Chuli and Rangrik Rang groups.
