Ascent Trip Report

Climbed South Sister solo, using the route that starts at the Devils Lake TH. Weather was cloudy and 70 at start. About 8100 feet broke through most of the clouds and the weather remained bright and sunny and about 75, until I went back down through the cloud layer at about 7000 feet on the descent.

Originally planned to ascend South Sister as part of a 4-person Boealps 3 Sisters Marathon July 26-28, but North Sister routefinding and dangerously loose rock cost us so much time that sufficient time did not remain to climb South Sister. I returned on August 1 to attempt it myself.

The loose steep scree was omnipresent from about 7500 feet on up. Avoided glacier travel since I was solo and unroped. Skirted the edge of the Lewis Glacier and the Summit Crater Glacier.

Successfully summitted. A bit of an exposed scramble to the tiny summit on the crater rim. Amazing views. See my Facebook page for photos of the trip.
