Avalanche Summary

A small wind slab was observed out of steep, rocky terrain on Monday. Otherwise, no new avalanches were observed.

Snowpack Summary

The snow surface consists of wind-affected snow in exposed terrain at higher elevations, soft snow in shaded and sheltered areas, and a melt-freeze crust on steep southerly slopes.The middle and lower snowpack is well-settled.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
