Snowpack Summary

5-10 cm of snow sits above the recent November rain crust which goes as high as 2200m in the terrain. Total snow pack height in alpine is around 45-85 cm and sits on top of a variable weak basal crust from early October. A variety of surfaces can be found in the alpine from wind pressed/scoured features to wind slabs in the lee in the high alpine.

Avalanche Summary

A field team yesterday reported no new avalanches but signs of wind transport in the high alpine peaks and ridge tops.
