New Snow Density: 
Low

Powder
Dense Loose
Wind Crust

5" new in sheltered areas, low density stellers.

Exposed areas at tree line and in the alpine were a mixed bag of wind crust, drifts, slabs and scoured areas.

Red Flags
Red Flags: 
Recent Avalanches
Wind Loading
Cracking
Poor Snowpack Structure
Avalanche Problem #1
Type: 
Wind Drifted Snow
Trend: 
Same
Problem #1 Comments: 

Wind slabs were my biggest concern today, generally localized with a moderate hazard.  The thing to remember about east winds is that they can surprise us with wind slabs in typically sheltered as well as odd areas.

Avalanche Problem #2
Type: 
Persistent Weak Layer
Trend: 
Same
Problem #2 Comments: 

The basal facets are still sitting above the ground, I think the overlaying slab is bridging and gaining strength.

Moderate hazard with the potential for serious consequences.

Snow Profile
Aspect: 
Southwest
Elevation: 
11200
Slope Angle: 
25
Comments: 

Of note in the above pit profile is shovel shears in the basal facets and above a 5mm knife hard crust mid pack, ECTN with a lot of weight applied at end.  I dug the pit at this location to look for facets at upper elevation south aspects, not disappointed!

Photo of facets below, remember this is on a south aspect.....I am use to seeing this in Canada not Utah, time to get used to a new area!

Photos of two recent avalanches below.

North aspects on Lake Peak consist of basal facets below a supportable 2 finger slab capped with 5" of low density snow.  The low density snow may not support much of a load if the storms predicted for next week come through as predicted.  This would be the initial primary hazard.

Sleds were still bogging down a bit into the basal facets

Overall a Moderate hazard, I did nor see anything alarming in any of the areas traveled today
