The Climb
From the 8,980-foot connecting saddle, scramble northwest up through pine forest then steep talus/scree to reach the base of the summit block. Climb a chute on the right/northeast side of the southeast face to reach easier, blocky terrain just prior to reaching the summit high point. The summit of Summit Rock has a USGS benchmark but no summit cairn.

The Descent
From the summit, descend the ascent route to the base of the summit block. From here, scramble south through dense pine forest with copious blowdown to reach the Custer Motorway and your parked vehicle. You avoid the unpleasant connecting saddle with this descent route, but you still have a lot of awful blowdown and steep, loose scree/gravel to contend with. It is a more direct route back to the Custer Motorway but it is no picnic.
