Wyoming, Grand Teton National Park, Teewinot. On July 16, John Reisinger (25) and Gary Smith (18) had completed an ascent on Mt. Teewinot and were descending, unroped, via a snow-filled couloir. Reisinger began to slide out of control and before he could effect a selfarrest he had slid about 30 ft. down the snow and onto some rocks where he tumbled another 10 to 15 ft. suffering injury to his arm. Smith put the arm in an improvised sling and assisted Reisinger during the continuation of the descent. Reisinger was taken directly to St. John’s Hospital in Jackson.
