John Slemp survived a 1500 ft fall from Mount St. Helens. This past Saturday while on a family trip, he and his son crawled to overlook a hanging crevice of the mountain, where the snow broke loose and Slemp fell 1500 ft. Slep originally fell 150 ft, but while trying to regain his original position the snow broke loose again and he fell another 1300 ft.
Slemp was completely conscious and fully aware during the entire rescue process, which helped the helicopter spot John who was waving and picked him up with the helicopter.
