This slide was triggered by a snowmobiler in the Lionhead area near West Yellowstone last Tuesday (2-19). Fortunately nobody was caught. Although this slide was triggered nearly a week ago, it's a good reminder of what's still possible in the backcountry. Photo Brett R.

We investigated this south facing avalanche that was snowmobile triggered on Tuesday, Feb 19th. The avalanche was a hard wind slab sitting on facets. It was up to 3 feet deep and was likely trigggered from the thin part of the slope. The slide ran 525' vertical and was 300' wide with an average slope angle of 40 degrees. Thin areas of a slope are where avalanches can be initiated from. No one was caught. Photo: GNFAC
