Avalanche Summary

No new avalanches have been reported recently.

Snowpack Summary

Eastern areas saw 10-15cm new snow in the last storm, while western area just a trace. This new snow overlies old wind slabs on higher north and east facing terrain and sun crusts on solar aspects. Wind slabs are extensive in exposed areas and cornices are reported to be well developed. A surface hoar/facet/sun crust layer from mid February (12th) may be buried in the top 20 cm or so, where it hasn't been blown away by the wind and is likely making some of the wind slabs more touchy. Mid and lower snowpack layers are generally well settled and stable.
