Avalanche Summary
Numerous size 1 loose wet avalanches were reported on Saturday. They failed in steep rocky terrain in response to warming and solar radiation. On Sunday cornice failures to size 2 were reported. Several small wind slabs from immediately lee of ridge crest were reported Monday.
Snowpack Summary
Light accumulations from Friday may now exist as a soft wind slab in high elevation lee terrain. The new snow overlies older wind slabs, crusts and wind-scoured surfaces. Sun-exposed slopes and lower elevation areas are likely in a spring melt-freeze cycle. Weaknesses buried in the upper snowpack may include hard crusts and/or facet crystals, although not much is known about the reactivity or spatial distribution of this layer. At the base of the snowpack, weak facets may be found. Cornices are large and potentially fragile.
