Watch for small wind slabs developing on Sunday as winds increase. Early season conditions exist...but if the snow is deep enough to ride, it's deep enough to slide.

Avalanche Summary
No new avalanches have been reported in the past few days. Observations are limited this time of year, please consider filling out a MIN report.
Snowpack Summary
Expect early season conditions with a shallower than average snowpack, at treeline depths are between 30-80 cm. Below treeline snowpack depths taper off quickly.
Surface conditions are variable. A sun crust can be found on some steep south and west facing slopes, and wind effect exists on exposed terrain at treeline and above.
A crust with facets or depth hoar exists at or near the ground.
