Quick report
- Red Flags
- Cracking, Collapsing
It seems as though the active weak layer is about 2 feet down from the current surface in wind sheltered areas. Areas that are sparsely treed or open appear more prone to have whoomphing and settling. See pic of crack that propagated.

- Instability Comment
- <p>On a skin up from the Loop Road to the ridge above the winter trailhead, I encountered at least 5 instances of significant settling accompanied by whoomphs. It appeared that this settling was occurring about 2 feet deep into the snowpack. In one instance, above the winter trailhead, on a north facing slope about a 35* near the ridge, a 15 foot long crack propagated from either side of a small stump (see pic).</p> <p>I encountered significant wind drifts on leeward slopes up to 4 feet deep. </p>
