North Ridge of Peak 11,585. The northern aspect of this peak has two facets, a concave north face and a spectacular northwest face, both of which probably have too much rotten rock for good climbing. The separating ridge, however, is of excellent rock and rises from the canyon floor in four steps of moderate difficulty. William Buckingham and Barry Corbet on August 16, 1957 ascended this ridge, the first climb on the north side of the peak. A pinnacle at the base of the third step provided an interesting climb. They climbed the summit wall directly over steep slabs to the regular summit ridge.
