Middle Sister


Basic Alpine Climb - Middle Sister

First preference given to Olympia BC students in need of a Basic Alpine Climb. A 2 night 3 day climb to the top of Middle Sister in the central Oregon 3 Sisters Wilderness. The trip is a very beautiful and moderately strenuous trip involving 2 nights of camping(likely on snow) 5 miles in from the Pole Creek TH, and Saturday climbing a portion of the Hayden Glacier to the North Ridge of Middle Sister, and from there up to the top. We will return Sunday.
