Avalanche Problem #1
Problem
Persistent Weak Layer
Trend
Same
Problem #1 Comments
no deep PWL found on this SE slope at 9200 but there was a nasty MF crust 15cm from surface that failed at ECTN 11, yet did not propagate.
Additionally, the sun got the best of the surface, despite temps staying low 20s, so we now have a future weak layer for next storm and beyond, and the Solar aspects can soon give us the business.

Wind Drifted Snow
