Snowpack Summary

18 cm total storm snow over the last three days. Stubborn buried windslab found in open areas in top 30cm on N through E lee aspects. The Oct 25 MFcr is between 2-5cm thick and down as much as 80cm, most prominent on N-NE lee features. Hard collapsing failure observed 10cm below this crust. Early season hazards still present, and hazardous! 

Avalanche Summary

Mostly dry loose activity observed from steeper solar terrain.
