Snowpack and Avalanche Discussion
Bridger Range Madison Range Gallatin Range
Lionhead area near West Yellowstone Cooke City
Yesterday, the snow flew and the winds blew. On some slopes, the new snow bonded well to the old snow surface. On others, sensitive soft slabs were easily triggered by local ski patrols conducting avalanche mitigation and by backcountry skiers.

This time of year avalanche conditions can vary as much as the weather and change equally as fast. The good news is that temperatures dropped below freezing last night. These cold temperatures refroze the snow surface and will limit wet avalanches today but not eliminate this problem completely.

A combination of warm temperatures and a lack of loading has created generally safe avalanche conditions. We have found many stable slopes recently in Beehive and Bear Basins, Hyalite Canyon, and Lionhead near West Yellowstone. Even wind slabs seem to be well bonded.
