Yesterdays colder snow had become damp by today.  Some rime on trees but not enough to matter for skiing.

Red Flags
Red Flags: 
Recent Avalanches
Wind Loading
Poor Snowpack Structure
Avalanche Problem #1
Type: 
Persistent Weak Layer
Trend: 
Same
Problem #1 Comments: 

Weak snow is easy to find along the Park City Ridgeline.  All it takes es stepping out of your skis and you sink in quite far.  In addition to basal facets, there are also weaknesses around the rain crust below say 9000 feet and buried near surface facets above.

Avalanche Problem #2
Type: 
Wind Drifted Snow
Problem #2 Comments: 

I was surprised at how firm and stubborn some of the wind slabs felt along the ridgeline.  This can lead to a false sense of stability because the snowpack "feels" strong and may not crack easily like more sensitive wind slabs might.

Comments: 

Extended column tests provided an audible sudden collapse but not an obvious rapid planar shear.

This slope had been extensively tested by small animals.  The bobcat (maybe? larger tracks in foreground) seemed to have a better sense of the avalanche danger and stuck to the ridge.
