Avalanche Summary
Some small soft slabs and loose dry avalanches were skier triggered yesterday in steep convex terrain.
Snowpack Summary
20 cm of new snow fell from the recent storm with moderate winds creating touchy soft slabs at treeline and most likely thinker and harder windslabs in the alpine on Easterly aspects. Indeed, snowpack test showed easy result within the storm snow. This new load is sitting on the Late November surface hoar layer now down around 100 cm and the early November crust down 200cm. Because of the stability tests variations (from no results to suddan planars), the limited quantity of observations and significant depth of those layers, they remain the primary concerns.Â
