Avalanche Summary

Recent avalanche activity is limited to isolated thin windslab releases to size 1 in the alpine.

Snowpack Summary

Recent low density storm snow has been facetting due to the cold temperatures. Variable wind effect has created wind slabs in the alpine. Watch for a recently buried layer of surface hoar down 30-40cm that may develop a poor bonding layer. The depth of the mid-november crust is also variable across the region. Reports have the crust down between 100-200 cm and snowpack tests have produced a variety of results from moderate and sudden to hard and resistant, and in some cases no result. If you dig down to the crust, watch for facets developing above and/or below. This may provide a weak layer above a smooth sliding surface in the future.
