COLD! A 2 puffy day. Winds were light below treeline but there was transport off of the high peaks in the morning. Also a bit breezy upon my arrival at 8.30 but the wind subsided at this elevation (10,000')
Snow Characteristics
New Snow Depth: 
19"
New Snow Density: 
Medium
Snow Surface Conditions: 
Powder
Wind Crust
Snow Characteristics Comments: 

19" seemed to be the consensus between snotel and Eagle Point.  The storm came in damp and warm with graupel at the base.  Basal snow was high density grading to medium density.  Low angle skied well.  Thin exposed areas still felt a bit hollow and punchy.

Some wind crusts and drifts in exposed areas.

Red Flags
Red Flags: 
Heavy Snowfall
Wind Loading
Poor Snowpack Structure
Avalanche Problem #1
Type: 
Wind Drifted Snow
Trend: 
Same
Problem #1 Comments: 

My #1 concern is wind slabs in wind exposed areas.  I mostly stayed out of this type of terrian but wind affect was visible in many places.

Considerable danger mostly at or above tree line.

Avalanche Problem #2
Type: 
Normal Caution
Trend: 
Same
Problem #2 Comments: 

Normal caution for a thin early season snowpack with underlying basal facets.

Moderate danger

Two snow profiles demonstrating variability in the snow HS pack due to wind

HS is 35 for the 1st and 26 for the 2nd.

Both profiles contain 4-5" dry of 4-finger basal facets.

The basal facets are overlain by 12-16" of rounds.

Both profiles are capped by 12-19" of storm snow with graupel at the base.  ECTs were variable in this graupel ranging from ECTN to ECTP 12, Q2.

Of note in the 1st profile (HS34) is a subtle rain crust below the graupel.  I might have missed this in the other profile.  I found it after being told about the rain event and had to look/feel with a bare hand.  It is marked by the orange Voile strap.

Overall all hand pits and profiles in this area were consistent with the exception of HS.

1.  facets

2. rounds

These profiles were taken within the Eagle Point Boundary but represent backcountry conditions for NW aspects at this elevation.  Today was opening day and the slopes were unskied or touched until today.

I did not see any natural avalanche activity from the last storm cycle.  I think things got heavily plastered due to the storm coming in warm and wet.

Overall a moderate danger below tree line and considerable in wind exposed ares at or above tree line.
