Rapid Warming
Poor Snowpack Structure
Red Flags Comments
Biggest concern today was wet activity with the strong solar and rapid warming. Not great snowpack structure but unable to get propagation or energy in tests. Quick hand pits showed high spatial variability across slopes in both total snow depth and slab depth.

Good day to stay out from under south facing sunny slopes. By 1200, widespread small loose activity noted on south facing paths above little cottonwood.

Decreasing Danger
Problem #2 Comments

Stability seems to be improving as the snowpack is healing. Snowpack structure isn't great with buried weak layers/ slabs still present but not reactive. Shallow repeater paths that have slid multiple times this year seem to be most suspect.
