About Elephant Buttresses (Boulder Canyon Mouth)

Elephant Buttresses is the first climbing you hit when driving up Boulder Canyon — a south-facing Boulder Creek Granodiorite crag on the north side of the canyon at Mile 0.5, five minutes from downtown Boulder. Roughly 47 trad routes plus 17 boulder problems on dense 1.7-billion-year-old Precambrian granite. South aspect and low altitude (1,646m — the lowest cragging in the canyon) mean it dries within an hour of a summer shower and stays climbable through most of winter on sunny days. Roadside parking pull-off; USFS land, no fee. Boulder Climbing Community (boulderclimbers.org) maintains the approach trails and anchor-replacement schedule. Climbers planning a trip typically use Richard Rossiter's *Rock Climbing Colorado's Front Range: Boulder Canyon*.
