Mountain Weather

This morning mountain temperatures were in the high 20s and low 30s Fahrenheit. Winds increased yesterday afternoon. This morning they were averaging 20 mph with gusts of 30 to 40 mph from the Southwest. No snow fell overnight but a little snow was just starting to fall this morning. Don't get too excited because only an inch or two will accumulate today. Temperatures will drop a little by afternoon and winds will blow 15 mph gusting to 30 mph from the West.

Snowpack and Avalanche Discussion:

The Bridger, Gallatin, and Madison Ranges, the Lionhead area near West Yellowstone, and Cooke City:

The snowpack is mostly stable and generally safe avalanche conditions exist. Avalanches are a matter of timing, and now is a good time to ride in avalanche terrain. However, the probability of triggering an avalanche is never zero as illustrated by two recent, small slides near West Yellowstone.

Yesterday I rode on Lionhead, Doug skied in the southern Madison Range, and Eric skied in Hyalite Canyon. As in most parts of the advisory area, we found stable conditions, but there are two things to consider. One, a layer of faceted crystals exists 6 to 16 inches deep. Recent warm weather and a lack of stress from new snow have helped this layer gain strength. Since it's not buried very deep and could produce an avalanche, look for this layer and perform a few stability tests. Two, a new layer of faceted crystals (photo) and/or surface hoar (photo) exist on slopes sheltered from the wind where good powder can still be found. This layer will be a problem if enough snow falls to build a slab on top of it.

Today human triggered avalanches are unlikely and the Avalanche Danger today is LOW.

The next advisory tomorrow morning at 7:30 a.m. If you have any snowpack or avalanche observations, drop us a line at mtavalanche@gmail.com or call us at: 406-587-6984.
