Mount Trishuli West, a remotely located inaccessible unclimbed peak surrounded by Bangri Glacier, Mount Trishuli Main and Mount Hardol from south-west, north-east and south-east respectively, is approximately 45 km from Jumma (last road-head) on Joshimath-Malari axis. Being one of the most technically challenging mountains, this has become talk of the day in mountaneering circle. First attempt was made in 1939. Since then fifteen expeditions failed to climb this peak and four mountaineers have lost their lives. This year also, two foreign expeditions dared to attempt this peak. The British and German expeditions were beaten back. Koreans declared this peak invincible.

The Nehru Institute of Mountaineering (NIM) organised an expedition to Mount Trishuli. The NIM team was flagged off by the Chief Minister of Uttarnchal Mr Nityanand Swami. Establishing intermediate camp at Dunagiri (4000m), base camp at Bangni Kharak (4451M), Camp-I (5000m) on lateral morane, Camp-II (5518m) on Bangri Glacier near the base of the mountain, the team reached Camp-III (6341m). The team stayed at Camp-III for five days. Ropes were fixed to open the route further but due to hostile weather conditions the team came back to Camp-II. The team again occupied Camp-III. The route was opened to Camp IV (6638m). Inspite of the hostile weather conditions the route was opened and the seven member team including the leader reached the summit on July 17, last. Total 3000m of rope was fixed from the base to the summit. The mountain for the first time unveiled glimpses of its hidden treasures to the team.

The mountaineering team was led by Maj Kulwant Singh Dhami and the team members were Mr Rattan Singh Chauhan, Mr Laxman Singh Negi, Sub Amrik Singh, Hav Karamjeet Singh, Mr Jagmohan Rawat and Mr Soban Singh Bhandari.

The flag-in ceremony was held at NIM Auditorium, Delhi. Mr Jaswant Singh, Defence Minister was the chief guest and flagged in the team. He congratulated the team members.
