Points saillants

Assess for wind slabs in alpine terrain and pay attention to cornices.

Snowpack Summary

5 to 15 cm of dry snow sits atop melt-freeze layers. Several crusts may be found anywhere from 0 to 40 cm deep, depending on aspect and elevation.

The facet/crust layer that caused large avalanches in March is buried 100 to 150 cm deep and is unlikely to trigger under the current conditions.

Confidence

High

Avalanche Summary
