I stumbled across this article on the 1963 first (and only?) ascent of the Wickersham Wall on Denali's North Face by members of the Harvard Mountaineering Club. Summitposters may find it interesting reading.

Some quick googling suggests that as of now the climb is still unrepeated. Is anyone aware of a second ascent?
