Spiti 1955
In an expedition which set out to investigate the valleys around the Kulu-Spiti watershed, the party succeeded in making ascents of Guan Nelda and an unnamed peak c. 20,050 ft which formed part of a ridge dividing the Ratang and Parahio valleys. From the latter, they spotted numerous unclimbed peaks and identified a likely pass at the head of the Parahio glacier leading over the watershed towards the Parbati Valley in Kulu.
