Looking back across the Autobahn on CompassData’s summit approach. This north fac-
ing slope does not get sun until early afternoon and is the most dangerous part of the
trip. Running from around 17,200’ to 18,400’, the Autobahn is prone to avalanche, has
a large crevasse network at the bottom and succumbs climbers to extreme cold in the
morning and is crossed during maximum fatigue after a summit attempt. It is the first
slope to be managed after leaving 17,000’ camp, and the last challenge after a summit
attempt. In the background, Mt. Foraker looks on from 17,402.’
