Peak 12,000+ is the largest west sub-peak of the Mount Moran massif, home to a truly stellar and seldom visited ski mountaineering line we're calling the Twelve Thousand Couloir. Sustained 45 degree no-fall skiing on a 1,000 foot hanging snowfield, with a thin 55 degree escape crux, and 4,200 total feet of quality skiing to Leigh Canyon below, characterizes this "should be classic" descent.
