    A facet layer down 90 to 150cm has been inactive for a while, and we are gaining confidence that it is not a significant issue in the region. Large triggers, such as cornices, may be needed to initiate something deep.

Avalanche Summary

No new avalanches were observed or reported over the last 24 hours.

Snowpack Summary

Crusts exist on solar aspects to ridgetop and all aspects at treeline and below. North-facing alpine slopes hold 20–40 cm of dry snow. A stiff midpack sits on Jan facets 90 to 150cm, with a settled lower snowpack below. On most slopes, crusts over the slab add strength if thick and frozen.

Weather Summary

Saturday: Increased SW winds, mainly cloudy with a few cm of snow possible in the early part of the day. Solar impact should be minimal and alpine temperatures should stay below freezing. See image below for more details.

Terrain and Travel Advice

  • Even brief periods of direct sun could produce natural avalanches.
