Snow Profile
Aspect: 
Northwest
Elevation: 
10300
Slope Angle: 
25
Comments: 

HS 20-24" in general. 

Basal facets are 4-5" of 4-finger density, rounding, dry (see photo below).

Overlying snow pack grades from 2 finger upward to 4 finger.

Photo below:  Basal Facets.

Photo below:  In general I was able to isolate the snow pack to the ground.  This is one exception on a NW aspect at about 10,000', HS is about 14" in this location.  Column broke on facets.  This would be a concern with additional loading.

I was surprised that the snow is holding up and staying dry considering the above freezing or near freezing temps at 10,000.

The alpine has been blown very clear of snow in many places.  The area I went to ski on City Creek Peak was looking real thin.

Overall a low hazard in sub alpine areas and moderate in alpine areas where there are accumulations of wind drifted snow.
