Wind Crust
Snow Characteristics Comments: 

HST - 6" both in Fillmore and up high.  Some graupel.  Some sluffing on slopes approaching 40 degrees, minor but worth noting.

Red Flags
Red Flags: 
Wind Loading
Poor Snowpack Structure
Red Flags Comments: 
The basal facets are not going anywhere. I backed off a 35 degree north facing slope @8,500' after pole probing (photo below). Theses facets exist to below 7,500 feet but are below a rock solid crust below 8,000' on all aspects. Some isolated wind drifts up to 1' thick and soft slabs about 6-12" thick in places.
Avalanche Problem #1
Type: 
Persistent Slab
Trend: 
Same
Problem #1 Comments: 

Mostly on the north 1/4 of the compass above 8,500'.  Below that I think the crust is strong enough to support a big load.

 

Comments: 

No profile today, on many aspects, each storm has become part of the underlaying crust.

Photos below:

1. Isolated soft cracking with a slight bit of movement, none shooting.

2.  The slope I backed off of, 1' of hollow facets at the base of a 48" snow pack.

3.  Thin, lumpy (almost like moguls) snow pack @7,500', the crust is making it easy to travel.

4. Terrain and wind affect, the surface was a bit thick in this area (8,400'), looking down from photo 2.

Overall a low danger below 8,000', moderate elsewhere with the exception of considerable on upper elevation north aspects above 8,500'.
