Avalanche Summary

We haven't received any recent reports of avalanche activity.

Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

A dusting of snow will fall onto a widespread hard melt-freeze crust that is found everywhere except high-elevation northerly aspects, where soft snow may exist. Small wind slabs may be found on northerly alpine slopes from southwest wind.

Two weak layers that formed in February and March are found in the middle of the snowpack. These layers are currently dormant, but they could be triggered with a large load such as a cornice fall.
