South America, Ecuador, Obispo and Fraile Grande, Altar Group, 1981

Obispo and Fraile Grande, Altar Group, 1981. The Altar group consists of many peaks and pinnacles, which create the rim of a volcanic crater. Dave Jones and I climbed Obispo by its standard route, the south face. We bivouacked on the summit and then descended the long and difficult east ridge to the Obispo-Monja Grande col. From there we could descend to the glacier on the south side. This traverse took four days in late November 1981. In late December 1981 I returned with a Scot, Mike Orr and climbed the east ridge of the Fraile Grande, not a new route, and traversed the peak, descending the west ridge to a col from which we descended the glacier to the north.
