Mount Bonneville, West Face. The impressive west face of Mount Bonneville may be seen in line with the main street in Pinedale. In July Layton Kor, Dave Beckstead and I walked from Boulder Ranch to Rainbow Lake, then on the first full day hiked through the meadows past Sunrise and other lakes to this face. While Layton explored the face of Pronghorn, Dave and I made the ascent, first climbing drop-off snow slopes, then a steep left-curving chimney which contained some difficult free climbing. Eventually we arrived at a little notch on a frontal ridge, then climbed some five pitches on marvellous rock in a direct line to the summit. The rock was excellent, with almost continual difficulty. We used a total of 16 pitons, all for protection. Descent was by the south and west slopes.
