Quick report
- Cracking
- specific
We found dangerous avalanche conditions on the north side of the compass as we gained elevation to near treeline. 12" soft slabs were easy to trigger and ran naturally today, up to D2 in size and ~200' wide below ridgetop. Storm instabilities were smaller and less common below treeline in wind-protected terrain, though we also triggered and saw a few small natural storm slabs. The storm snow got moist or wet below 10,000', even on northerlies, thanks to greenhouse warming.
Minor cracking below treeline in sheltered terrain, where storm totals were about 10". Once we gained the ridge, it was easy to produce shooting cracks on leeward terrain features, about 12" to 15" deep at the storm interface (facets).Weather

Three large slab avalanches ran today on NE to E aspects NTL on Schuylkill Ridge. These broke at the storm interface, and were all on old bedsurfaces of repeat offenders (Great Wide Open, Thanksgiving Bowl, and Birthday Bowl). We also remotely triggered a similar avalanche in Yogis from about 20 feet away. Below treeline, there were a few small pockets that ran naturally (D1 storm slabs) and we ski triggered one. Warm temperatures and greenhouse conditions also produced a handful of small wet loose avalanches, both on sunny aspects and low-elevation northerly aspects.
