Pegasus Peak

Elevation: 11,736 ft
Prominence: 676

Climbing and access information for this peak is found on page 253. Derek Percoski and Dave Pahlas have provided the additional route information found below. Updated August 2019

Pegasus sits east of Surprise Valley and north of Standhope Peak. It is the northernmost most peak on a rugged ridge line containing two other 11ers, Andromeda and Altair. Rick Baugher and Chuck Ferguson made the first ascent in 1994.

Southeast Face, Class 3 by Derek Percoski

I climbed the SE face just east of the south ridge on Class 3 terrain. There are plenty of opportunities to improvise a scrambling route. A gully just north of Point 10727 also appears to provide a clear path. This information is primarily useful to a climber looking to do Andromeda in the same day, since accessing the southeast face would otherwise involve hiking past the standard route described in the book.

East Ridge, Class 3 by Dave Pahlas

Dave’s route traverses the peak his trip report is linked below. Dave describes the actual climb as follows:

“As we made our way up the valley, Pegasus came into view, and the east ridge looked like a nice direct route to the summit. We continued on until we were next to Big Black Dome (on our left) then veered to the right, and headed up the small valley north east of Pegasus. Once at around 9900’, we climbed the talus to the south, and made our way up to a scenic shelf lake for a snack break. From here, we eyed a couple lines to gain the ridge. We had axe and crampons, but I was suspicious that the snow would be too soft. Up we went to the base of the snowfields. The snow wasn’t bad, but the adjacent rock seemed stable, so we elected to take a dry route to the ridge. The rest of the climb was a walk-up, and we set a steady pace and made it to the summit by 12:30.”
