Clyde Palisade, Primrose Ridge. This prominent crest adorns the north face of Clyde Palisade to end on the west summit. It is very visible from Glacier Lodge and usually divides the light from shadow. Dave Black, Mike Graber, and I made the first climb in late July, taking most of the day from a high camp at about 12,000 feet where a rock outcrop breaks the glacier. Icy snow led to the lowest portion of the very thin crest (this is just west of the spur that continues north). From here 13 demanding pitches took us to the summit, with each pitch religiously staying on the crest; 3 of the pitches were a minimum of F9. NCCS IV, F9; all chocks.
