Avalanche Summary

No new avalanches were reported in this region on Friday. However, field observations are currently very limited.

If you are getting out into the backcountry, let us know what you are seeing by making a post on the MIN (Mountain Information Network).

Snowpack Summary

Strong solar radiation has created moist snow on sunny aspects at all elevations.

Up to 25 cm snow sits on a crust everywhere except north facing aspects at upper elevations where the snow remained dry.

Lingering wind slabs may still be reactive on lee features below alpine ridgetops.

A series of crusts exist in the upper snowpack.

Expect difficult travel at lower elevations with thin snow coverage.
