St. Peters Dome is a historical and prominent feature of the Columbia Gorge. St. Peters Dome is a decomposing monolith of volcanic rock that was fairly popular up till the 1960s but now relatively few climbers set their sights on this serious endeavour. An ascent of the Dome by any route is a very technical endeavour involving considerable risk. St. Peters Dome is a piton-required nailing aid climb on a vertical wall of cobblestone chunks of friable rock.
