The snowpack has been slow to improve since last week's storm. Human triggering is still a very real concern. The weak and shallow early-season snowpack produced widespread whumpfing for field teams today.

Snowpack Summary
Observed a large portion of the area today on monthly snow study flight. Lots of wind transport at Alpine and Treeline elevations due to moderate to strong winds out of the West. Wind slabs are prominent in all lee and cross-loaded terrain at higher elevations. Whumpfing was widespread in areas traveled today. Total snowpack depth varied from 70 to 120cm deep. Previous storm snow has now settled to an average of 65cm at 2200m. The November rain crust remains prominent about 20 to 30cm off the ground, and there is a layer of facets above the crust.
