Hallett’s Peak. On July 27 Yvon Chouinard and Ken Weeks started up the north face of the third buttress. Instead of climbing the prominent chimney, we went straight up the face and rejoined the regular route at the next to the last patch. No direct aid was used. This variation was considerably more difficult than the regular route.
