No new avalanches have been noted.

Snowpack Summary

Expect to find wind slabs in the alpine and loose snow in sheltered areas. The two layers that are being tracked right now are:

1. Several generations of wind slabs in the upper 40cm of the snowpack producing moderate to hard test results.

2.The November 5 crust is sitting about 50cm off the ground. You can find up to 10cm of facets sitting overtop of the crust and still producing test results on the facets. This layer is found all the way into the alpine.

Terrain and Travel

  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
  • Approach lee and cross-loaded slopes with caution.
