Avalanche Problem #1
Type: 
Normal Caution
Trend: 
Increasing Danger
Problem #1 Comments: 

Today it was normal caution.  Nothing alarming noted in areas traveled.  There is not much of a slab in the thin faceted areas.

Generally low danger below treeline.

Avalanche Problem #2
Type: 
Wind Drifted Snow
Trend: 
Increasing Danger
Problem #2 Comments: 

I would speculate that wind slabs would be an issue in the alpine. I stayed at or below treeline today.  Many areas looked drifted and wind affected.

Moderate hazard.

Snow Profile
Aspect: 
West
Elevation: 
10800
Slope Angle: 
20
Comments: 

This profile was taken right below tree line in a semi-sheltered area.

HS-38"

Bottom 8" are basal facets, 4 finger, dry and beginning to round (photo below).  Above that the rest of the snow pack grades from 2 to 4 finger hardness.  Most of the 2 finger snow is verging on 3 finger and appears to be weakening. A photo of the 2 finger grains is included below.  They are mostly rounds or facets verging on rounds.

Upper 3" is new snow.

Photos below:

1,  Basal facets; and

2.  2 Finger rounds

Overall his is a stable snow pack.  However things are highly variable in this area.  Within 200-300 feet I was able to find rotted shallow faceted snow (photo below).

Photo below:  Surface hoar.

Photo below:  An area of weak shallow snow less than 300 feet from the profile above.  This area was scoured during the last storm and has a HS that is significantly less than shown in the profile above.

Overall I would say a low danger with pockets of moderate in areas traveled today.

I would expect the hazard to rise quickly to considerable with forecasted snow tomorrow.

The Eagle Point Ski Patrol does not mind if folks to stop in when touring from the upper lot.
