Accident Summary

PRELIMINARY REPORT: On Friday May 10, two experienced backcountry skiers were traveling on Donaldson Peak in Idaho’s Lost River Range. While downclimbing to their ski descent, Skier 1 triggered and was caught in a small wind slab avalanche. The slide carried Skier 1 downhill, triggering a second and larger avalanche. Skier 2 used a satellite communication device to call for help before descending the avalanche path. She located Skier 1 with her rescue transceiver and probe pole. Skier 1 was buried under at least 5 feet of snow. She dug Skier 1 out of the snow with her shovel and began CPR. Search and rescue teams responded and evacuated Skier 1, but he did not survive the accident.
