There’s a surprising number of alpine routes on the Boott Spur Buttress on Mt. Washington. Some are primarily snow climbs, like Cathedral, Stovepipe, Dodge’s, and Hillman’s. Others, such as Summer Chimney and Autumn Arete, are rock routes that ascend one of the three rock buttresses (the aptly named Buttresses No. 1, No. 2, and No. 3) that guard Boott Spur’s upper reaches.
