Wyoming, Grand Teton National Park

Wyoming, Grand Teton National Park. On 18 July, Lendol Leach (19) and six companions had gone on an overnight trip to Waterfall Canyon. They had left the marked trail and got into what was described as off-trail rock scrambling. While they were attempting to ascend a steep rock and brush covered slope Leach slipped and fell to his death.
