Avalanche Summary

No new avalanches were reported on Saturday.

NOTE: Observations are currently very limited in this region.

Snowpack Summary

Up to 10 cm of recent snow may be found at upper elevations. This snow overlies a robust crust everywhere except northerly aspects at upper elevations. Recent westerly wind may have formed small wind slabs on lee aspects at upper elevations.

Most terrain has undergone strong melt-freeze cycles, creating a strong, well bonded snowpack. The one exception could be northerly aspects at upper elevations, where deeply buried weak layers may still be present.
