Snowpack Summary

Around 10-20cm of recent snow sits on a newly formed rain crust. At alpine elevations, recent storm slabs and wind slabs may still be sensitive to triggers like the weight of a person. Deeper in the snowpack, weaknesses such as loose sugary facets and crusts exist in some locations. A recent snowpack test from the Hankin-Evelyn area produced easy/moderate pop results down 30 cm on one of three buried crusts.

Problems

Wind Slabs

Wind slabs may be found behind terrain breaks like ridges and ribs. In certain areas, a slab could fail on a deeply buried weakness, creating a surprisingly large avalanche.

Use ridges or ribs to avoid wind loaded and cross loaded slopes.>Choose well supported terrain without convexities.>Avoid areas with a thin or variable snowpack.>
