Snow Characteristics Comments

Wind crust everywhere except in the sheltered trees made for 'adult skiing'. Still nice turning in the sheltered areas with 4-5 inches below 7500ft. on a supportable crust. Best option is low angle as the skiing is fast.

Problem #1 Comments

The wind slab was more stubborn today than yesterday in the Chilly Peak area. Still concerned with the hollow wind slab that fractured and cracked. See video. I believe this danger to be "considerable" on the higher exposed slopes.

Normal Caution
Problem #2 Comments

I was able to find the surface hoar layer and of course the rain crust. Even though there is a shear at each of these, there is no propagation on ECT. The wind slab seems to be the biggest danger and in places is sitting on grapple.

Comments

1. Wind affected slopes

2. Buried grapple

3. Short video of ski cutting wind slab on small east facing test slope
