Buck Mountain, Stewart Draw Buttress. A new area for convenient rock climbing was found by Yvon Chouinard and Kathrene Collins in July, 1980 on the buttress rising on the south side of Stewart Draw, the traditional approach for the regular route on Buck Mountain from White Grass Ranch. The first route, Peaches Direct, contains five pitches and lies near the center of the buttress. With one pitch of F8 difficulty the route ends at the uppermost pinnacle at the top of the buttress. A second route, Spigolo Nero, starts farther to the left, but also finishes at the top tower after F7 or F8 climbing. The short approach adds to the attractiveness of these climbs.
