Ascent Trip Report

Ken, Ryder, and I climbed Thompson Peak via the South Couloir Route. We began our climb from the large parking lot at Redfish Lake. We hiked the trail towards Marshall Lake. We wanted to camp at the small unnamed lake at about 7,700 ft elevation, so we left the Marshall Lake trail at about 7,700 ft and traversed over to the lake where we found a nice campsite at the outlet. In the morning we hiked around the north side of the little lake and then up the steep slopes to some ledges we could see above us. At about 8,700 ft we crested the ledges and found another nice campsite where we took a nice break. We then continued towards the large unnamed lake at 9,000 ft, we stayed high on the north side of the lake and continued west on easy terrain passing two more small snow fed ponds. At the last pond we were confronted with the headwall of the valley. This headwall looked nearly vertical and after consdierable discussion determined to go to the left where we could see some faint tracks from previous climbers where they had crossed the permanent snowfield. We crossed the snowfield and gained the ridgline. We then turned south and did a lot of rock hopping along the west face of Thompson until we could see a rocky route up to the south ridge of Thompson. Once on top of the south ridge, we could see the South Couloir route to the summit. The route is well used and it is easy to follow the climbers route. There is a short scramble at the summit to get to the highest rock outcropping. Fantastic views.
