Bugaboo Spire from the summit of Snowpatch Spire. (The North summit of Snowpatch in the foreground.) The Kain Route ascends the broken ground and ridge on this (S) side; the NE Ridge forms the right skyline. The Crescent Glacier is below, under the E. face. My 1990 edition of Green and Benson's Bugaboo Rock lists three routes on the 1,500' (460m) East face, but somebody else will have to write about those.
