Snowpack and Avalanche Discussion
Bridger Range Gallatin Range Madison Range
Lionhead area near West Yellowstone Cooke City
Warm temperatures and no new snow have greatly reduced the odds of triggering an avalanche. BUT, conditions are highly variable. Most observations indicate a fairly stable snowpack at the moment because the snowpack has not been stressed by the weight of new snow. However, the snowpack continues showing signs that triggering an avalanche on some slopes remains possible.
The sides of the gully are wind packed, dense slabs that are sitting on weaker facets. It took a lot of force to intiate a fracture (ECTP, 32), but it propagated which means avalanches are possible. Photo: GNFAC
