"Just before the accident Saturday morning, the two climbers were walking atop the narrow ridge between the ice walls. Cooley was climbing on the east side of the ridge, while Richards was on the west side. Cooley was about 50 feet ahead of Richards, and they were connected by a climbing rope.
Cooley, Gottlieb said, tripped on a crampon, slipped off the cliff to his left and fell about 30 feet. He was swinging like a pendulum when he hit his head on a rock.
Cooley's fall yanked Richards forward, and he found himself holding Cooley's limp body at the other end of the rope. Richards wasn't pulled over the ridge because the rope was tied to a harness in a way that absorbed much of Cooley's weight."
