1907: Dr. Tom Longstaff, Brig. Charles Bruce and A. L. Mumm, with alpine guides Alexis and Henri Brocherel, make a preliminary reconnaissance of the eastern and western sides of Kamet. The highest point reached is 6,100 m (20,000 ft) above the East Kamet Glacier. Longstaff deems the East Kamet route as too dangerous due to avalanche risk.
