Utah, Mt. Timpanogos

This narrative and analysis will cover the accidents of both Richard Lambert, m.D., and Richard Weaver because of the ironically similar events.

On June 8, 1980, Lambert (26) left for a solo ascent of Mt. Timpanogos via the Aspen Grove trail. From film retrieved from his camera, it appears that he followed the Grade 3 route via Emerald Lake to the summit. In late summer, this is a well-prepared and well- maintained trail. However, due to a heavy winter snowpack and an unusually large amount of avalanche deposition, the route was 95 per cent covered with consolidated snow.

Lambert was apparently descending a 30°-snowfield in a natural wide drainage when he either lost control of his glissade or unknowingly crossed a thin area at the edge of a 100-foot vertical rock band. He apparently fell through the snow, plunging into a large, cavernous moat created by a six-foot wide, three-foot deep stream. He fell free for 75 feet into the stream which formed a 75–100-foot waterfall before it disappeared beneath the snowpack. Lambert was not reported overdue until 9:30 a.m. on June 9. The delay in the report was due primarily to the fact that he and his sister had been overdue in the same area the previous week and had walked out before a search was organized. His sister felt that he had probably spent the night at the Emerald Lake Shelter.

On June 9, 1980, Richard Weaver (26) and his brother Roger (18) followed the Aspen Grove approach to Emerald Lake. After reaching the lake they began a glissading descent wearing tennis shoes. Richard was several hundred feet below Roger on the same 30°- snowslope that Lambert had descended when he lost control and plunted through the same opening leading into the large moat. He fell approximately the same 75-foot distance into the water and died around 10:30 a.m. When Roger saw that Richard was lost, he rapidly descended for help.

The rescue team responded to the search for Weaver without any knowledge of Lambert’s whereabouts. After finding a passage into the cavern, the team was able to locate a body in the stream at the base of the waterfall. Because the water greatly hampered visibility and created a very cold atmosphere, the team quickly removed the body without further search for articles, etc. At the base of the mountain, it was determined that the body was not Weaver but Lambert. A second descent into and search of the moat resulted in the finding of Weaver’s body underwater and 15–20 feet downstream. Both victims suffered major head injuries and both had compound fractures of upper and lower extremities. (Source: Dr. Richard Wallin, Salt Lake City, Utah)


Lambert was traveling alone and without an ice ax. Had he been reported overdue earlier, it is doubtful that the outcome would have been different except that Weaver’s accident might have been averted, as the United States Forest Service closed the area until the snows cleared. Weaver’s accident was caused in part by the fact that he was wearing tennis shoes and had no ice ax. We are all reminded by these accidents that traveling on spring snow slopes, with the ever present potential danger of streams underneath and moats, should be done with ropes, as one would in glacier travel.
