Edward Tom, 40, of Boulder was scouting for a campsite following a storm when he plunged off the cliff in Garnet Canyon shortly before 6 p.m. local time, park officials said Saturday.
Two doctors who were climbing in the area rappelled to Tom but were unable to revive him, The Denver Post reported.
His body was recovered Saturday.
Tom and a climbing partner had planned to camp overnight in an area called Petzoldt Caves, then scale the 13,770-foot Grand Teton Saturday morning, the newspaper said.
