Kernpunkte

Snow is forecast to fall through Thursday. Before committing to a ski line make sure to test how the snowpack is reacting to this new load and remember there are numerous early season hazards just below the surface.

    The snow pack is very weak at the bottom. Natural activity has not been observed yet. Keep this on your radar as triggering remains possible with the shallow nature of the overall snowpack.

Avalanche Summary

A few small wind slabs reported at ridge top at Marmot Basin over the past couple of days. Widespread spin drifts were noted off steep rocky terrain due to the strong winds on Wednesday.

Snowpack Summary

The snowpack is 40-60cm deep and is weak and facetted. A surface hoar layer is down 15-20cm below 2300m. Strong winds have stripped exposed alpine and tree-line terrain and created wind-slabs in cross-loaded and lee features.
