Avalanche Summary

Snowpack Summary

The upper snowpack is largely well settled and non-reactive.  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.
