Thorson Peak, South Buttress. A party of eight, including Arnold Bloomer and Keith Spencer, approached the peak via the Jefferson Lake logging road early in the season. A mile above the lake the mountainside was ascended to a chute at about 4000 feet. This led directly to the buttress, which was ascended to the false summit. The exposed ridge was followed west-northwest to the rocky summit.
