Notes
On the morning of March 23, 2023 near Daisy Pass, two snowmobilers were stuck on a slope and a third was snowmobiling up to help when a large avalanche was triggered. The two stuck riders were caught and carried, and one of them sustained potentially life-threatening leg injuries (later determined as a broken femur). The third rider was able to safely ride off the slope and was not caught by the avalanche.
One rider in the group rode into Cooke City to contact Search and Rescue. Cooke City/Park County Search and Rescue transported the injured rider back to Cooke City where he was transferred to an air ambulance.
The avalanche was on a southwest facing slope at 10,000’, it broke up to 4’ deep and 150’ wide, and is classified HS-AMu-R3-D2-O.
