Peak 10585 (commonly known as Summit Creek Peak) is located above the southeast fork of Summit Creek, off of Trail Creek Summit, in the Pioneer Mountains. Summit Creek Peak is a ranked peak and is often climbed along with an ascent of the unranked peak that you pass along the way, Phi Kappa Mountain.
Take Trail Creek Road either from west of Mackay off Highway 93, or northeast of Sun Valley, to the marked Trail Creek Summit. There is a parking area on the southeast side of the pass summit.
Southeast Ridge Ascent, Southwest Face Descent Route, Class 2+
Just off the parking area, find a well-traveled trail that heads southeast. Take the trail as it parallels the southeast fork of Summit Creek all the way to the pass between Phi Kappa Mountain and Peak 10860.
Here, go off trail and follow the southeast ridge, traveling northwest, toward the summit of Phi Kappa. As you will be so close to Phi Kappa’s summit at this point, tag it and take in the views.
Continue traveling northwest along the ridge to the summit of Summit Creek Peak. It’s easy to travel along the ridge and the summit is marked with a cairn. From the summit take note of the Southwest Face of Summit Creek Peak. It may look a little imposing but if you enjoy scree skiing, definitely take this face down. At the base of the face, you will have to cross Summit Creek. Depending on the time of year, it could be a challenge. There are no bridges but there are doable crossing spots because of deadfall. When you regain the trail continue toward the parking lot (northwest).
If you don’t want to come down the face, backtrack the ridge southeast and obtain the trail where you left it at the pass and hike back out to the parking area.
Margo Mandella provided her GPS track from her, Steve’s, and Bruce Dunham’s 2017 ascent. (Note the position of North arrow. Additionally, the track is yellow, the blue is the boundary between Custer and Blaine counties.)
