Primary Problem: Wind Slab
Bottom Line: The primary avalanche concern is wind slab avalanches where yesterday’s strong wind drifted recent snow into slabs up to a couple feet thick. These slabs are possible for a person to trigger today. Avoid steep, recently wind-loaded terrain, typically found near ridgelines, identifiable by cornices above or a textured or rounded snow surface. Near West Yellowstone, weak layers buried in late January continue to result in persistent slab avalanches up to 4 feet deep. These slides have not been huge, but large enough to be deadly, especially in much of the terrain where they have occurred, with trees or depressions at the bottom where snow can pile up deep.
