Access
Same as for Mackay Peak on Page 262 of the book [FSR-207/Rio Grande Canyon Road (A)(3) on Page 264]. This ridge traverse (from Mackay Peak to White Knob Mountain) is part of a 3-peak adventure that includes Mackay Peak, White Knob, and White Knob Mountain.
Northeast Ridge, Class 2
The Climb
From the 9,820-foot connecting saddle with Mackay Peak, follow the narrow, then rounded, ridge crest for about a mile to reach the summit of White Knob. The ridge terrain begins as an easy mix of tundra and broken rock until the ridge steepens considerably. The ridge crest is now steeper, rockier, and whiter and requires scrambling up Class 2 layers of slabs/boulders with ramps in between. White Knob truly IS a white knob of white quartz and other whitish rock. The summit has a large, torn-down cairn.
Southwest Ridge, Class 2
The Descent
From the summit, follow the ridge crest southwest to reach the 10,260-foot connecting saddle with White Knob Mountain. The ridge terrain on the southwest ridge is mostly a mix of talus and thick tundra. It is a bit tedious but is just under ½ mile in length.
