Named after the famous author, Owen Wister, Mt Wister is not frequently climbed, but does provide impressive views of Buck Mountain and Garnet Canyon. This route up the northeast couloir is the most straightforward method that leads to the summit. Before Lake Taminah, you'll cross over the outlet stream and onto the glaciated ledge. After ascending the loose talus and scree slope, climb through the broad couloir on the east ridge. Scramble up the left edge of the ridge to the summit. An ice axe is necessary, especially in early and mid-season.
