Avalanche Problem #1
Type: 
Normal Caution

Same
Problem #1 Comments: 

Normal caution for traveling in a thin snow pack.

Moderate hazard, due to the presence of above described facets in low density areas below denser snow.  Not a right side up profile.

West
Elevation:

Slope Angle:

Comments: 

HS-24" Gloves are sitting on crusts.  The lower is melt/freeze and the upper wind/warm.  Basal facets below the lower crust are chained (photo below).  ECTN in this area.  I was able to only collapse the area where the force was applied until in compressed to the ground, similar to the photo in my 2nd pit.

2. Chained facets.

An additional pit on a north aspect in upper Copleys Canyon.  HS-28".

Photos:

1. Pit showing the same crusts as in snow profile.  Of note there is a knife+ hard crust sitting on the ground.  Above this crust are chained facets sitting below the melt/freeze crust.

2. Chained facets.

3.  ECTN

4.  Terrain photo, The only reason I did not ski this area was I ran out of time after a rather long approach.

Photo below:  Typical west facing terrain in Mountain Sheep Canyon.  Still a thin snow pack and early season conditions.

Overall, I did not see any sign of wind affect that I saw 2,000+ feet higher yesterday in the Tushers,  I would say moderate hazard mainly because of the facets which appear to be healing but still are not that far below the surface.
