New Snow Density: 
Low
Snow Surface Conditions: 
Powder

Rain-Rime Crust
Snow Characteristics Comments: 

Very little wind damage with small isolated patches of wind crust and lingering rime crust observed in the most exposed areas. The graupel from yesterday served as an excellent rebounding/spongy turning base with the 4 to 6 inches of new light density snow from last night on top. Very good riding, especially on ENE, NE, N and NW aspects. You could feel the old surface crusts on south, east and west aspects. 

Red Flags
Red Flags: 
Poor Snowpack Structure
Avalanche Problem #1
Type: 
Persistent Weak Layer
Trend: 
Decreasing Danger
Problem #1 Comments: 

It has been 9 days since the last human triggered persistent slab release, and this latest storm has not provided a substantial increased load in weight to test the buried facets. Despite this, all observations continue to report poor snowpack structure, and as a result this problem remains on the table. Many steep lines continue to be ridden, yet steep rocky and thin areas in the snowpack remain suspect. Due to this lingering possibility, the Danger out there appears to be moderate for these potential issues. 

 

Avalanche Problem #2
Type: 
Loose Dry Snow
Trend: 
Increasing Danger
Problem #2 Comments: 

Scattered/isolated natural and human triggered loose snow avalanches in the new snow only were observed. These all appeared manageable. 

See above regarding Sensitive Cornices. 

Wednesdays forecast for clear skies and temperatures reaching the upper 30's at 9000 feet should help initiate widespread wet loose activity on steep SE, S, and SW aspect.
