Avalanche Summary

Isolated loose wet sluffs have been reported.

Snowpack Summary

Isolated, stubborn wind slabs can be found behind ridges, ribs and on lee slopes (NW-NE). Sun crusts can be found on South and West facing terrain. The upper snowpack is showing continued settlement and gaining strength. Down 20-50 cm sits a persistent interface comprising of crusts, facets and surface hoar crystals. Recently, this layer has been reactive in very isolated, sheltered areas at treeline and below where surface hoar remains preserved. The mid pack is generally well settled with the average snowpack depth at treeline around 180 cm.
