Math majors aren't the only students hangin' out around Gerry-Hall these days. Rock climbers like Matt Holmes '00 regularly scale its 60-foot vertical face—though for who knows how long. The building is slated for demolition to make way for the north campus expansion. For three decades Gerry has been a testing ground for Dartmouth climbers. It is one of the few campus buildings where climbing is allowed. One climb on the north-facing side, named the Kandinsky Traverse after a splotch of paint on the wall by route pioneer Mark Sonenefeld '80, is so difficult that only one other climber, Neil Cannon '82, has completed the route. Given that the building is coming down, Cannon may well have been the last to make it up.
