Mount Adams, West Face of North Ridge. This previously unscaled 4000-foot wall was ascended on September 11 by Forrest Johnson, Robert Ostro and Robert Startzell and me. After ascending steep ice slopes and crumbling lava ridges above the lower Adams Glacier, we reached the summit snow dome immediately to the east of the upper Adams Glacier icefall after 5½ hours on the face. Owing to the lateness of the season, much black ice was encountered and we had to be continually alert for the ever present danger of rockfall. Descent was made by way of the north ridge.
