Miguel Carmona and I climbed this interesting summit from our camp at Dade Lake. The approach couloir is 35-40 degree steep and in late season requires ice axe and crampons. There are really two spires at the col. We climbed the higher, western summit. From the col, climb up and around (steep 4th) to the SW side of the western summit. From the notch between the two summits, climb steep 5.7 edge to the summit. In 1996, the only note on the western summit, was in old film canister. It said that in 1964, Dave McDonald and David Harvey climbed the route. We descended to the Abbot/Petit Griffon Col, scrambled up to the summit of Abbot and went down the NE Couloir which is an ugly pile of dirt and rocks when not covered with snow. This would be a great day outing for anyone wanting to climb a nice, airy, technical climb in the area. Recommended.
Lots of snow in the couloir when we climbed it. An excellent view from the top!
My Mount Abbot climb report:
With Vladimir. Fog and hail were fast approaching when we summitted at 5pm! Mount Gabb was a stunning sight.
