Black Canyon of the Gunnison, North Buttress of Chasm View. In May Rob Kiesel and I braved the regular descent gully, north of the northern rim of Chasm View. We crossed the river to the foot of the northern buttress of the south rim of Chasm View. The climb began in a crack system 100 yards left of the toe of the buttress on its east face. The sixth lead broke out left of the first crack system and went under a narrow roof into a new crack system that led eventually to a large brush patch at the end of the eleventh pitch. After scrambling to the upper right corner of the brush just a few feet from the buttress crest, we climbed a jam crack to a step on the actual buttress. A difficult free move gave access to the final, lower-angle leads of the upper buttress. NCCS V, F9, A3. In September Mike Wies and Wick Beavers climbed the buttress from its foot starting on the right side.
