This week's new snow buried a layer of facets sitting on an ice crust on a south facing slope off Henderson Ridge. This layering does not seem to be widespread, but the low test scores with a growing wind slab are enough to cause concern. Photo: GNFAC
GNFAC Avalanche Advisory for Fri Feb 3, 2017
Snowpack and Avalanche Discussion
Cooke City
The mountains around Cooke City picked up 3-5” of low density snow over the past 24 hours. This puts the four-day total at close to 3 feet. Light wind the past few days combined with a good bond between the new snow and old snow surface has kept avalanche activity to a minimum (video). This could all change as winds are forecasted to increase throughout the day.
