Late Saturday afternoon, a group of 3 snowmobilers and 2 snowbikers were in the Sheep Creek drainage, north of Cooke City. The two snowbikes were high on a slope near Miller Mountain when one stopped on a small ridge and the other climbed higher triggering a large avalanche. The avalanche carried him down through a gully and over a waterfall where he was partially buried. His arm and airbag were visible and his head was 1 foot under the surface. Resuscitation efforts were unsuccessful and Park County SAR evacuated the victim. The avalanche was 800 feet wide, averaged 2 feet deep (estimated) and ran 1200 feet vertical. The avalanche likely broke on facets and depth hoar at the ground in an area that was thinly covered and recently wind-loaded. The debris was up to 15 feet deep and the avalanche size is rated R3-D3. We will release a full report with details in the coming days. Preliminary information and photos are available here. Our condolences go out to the family and friends of the rider.
