Quimaraju and Huamashraju. On July 8 Woody (Curtis W.) Stark and I ascended Quimaraju (17,737 feet) from a camp above the icefall at the head of the Quebrada Shallap. Our new route ascended the north side of the peak and it involved a number of pitches of rock climbing in addition to snow and ice. On July 18 we climbed Huamashraju via the normal southwest ridge. The bergschrund was passed by a short sixth-class scramble up exposed rock on the ridge.
