Avalanche Summary

Avalanche activity has tapered off quickly since the storm. Explosive control on Monday and Tuesday produced size 1.5 wind slab avalanches. These slabs may still be triggerable by riders.

Snowpack Summary

Around 30 cm of wind affected snow sits over a mix of crusts, surface hoar in wind-sheltered terrain, and hard wind-affected surfaces. Reports suggest the recent snow is bonding well with the layers below. Low elevations received mostly rain while higher elevations received wet snow or mixed precipitation.

There have been a lot of great MIN reports in the last week from throughout the Lizard Flathead area.

The middle of the snowpack is generally expected to be well-settled and stable. Total snow depths vary from 100 to 150 cm at treeline.
