Avalanche Summary

No new avalanches observed

Snowpack Summary

The melt freeze crust on the surface was mostly non-supportive up to trreeline. Wind slabs in the high alpine on north aspects are still a concern for triggering. The melt/freeze crust is not expected to refreeze very well with Monday night's cloudy skies.  Avalanche danger is directly related to daytime heating and re-freezing of the melt/freeze crust.
