2. Southeast Face. The southeast face, a long snow slope interrupted by a short rock band, was climbed on return from Deluge Mountain, from camp near the tongue of Hatteras The route avoids pinnacles on the southeast ridge. This mountain may also be bypassed on the north by gaining the ridge south of the Hatteras-Krinkletop col and then descending north to the glacier. Round trip 11.5 hours. Glacier (III,4,s).
