Avalanche Summary

On Saturday, several storm slab avalanches were reported. Information is limited but the storm snow is reactive and needs time to bond.

Several large (size 2-2.5) storm slab avalanches occurred in the Lizard Range on Thursday.

If you head out into the backcountry, please submit a MIN. We look at every single oneðŸ™Œ

Snowpack Summary

Recent snowfall amounts are around 50 to 60 cm. In wind-exposed terrain, the new snow has likely stiffened into a slab and may be reactive to riders.The bottom of the snowpack has a crust from early November that is just above the ground. The crust has acted as a bed surface for recent avalanches.Snowpack depth is 100-180 cm at treeline.
