Snowpack Summary
10 cm of new snow has not yet built much of a slab over the previous drought layer (surface facets, surface hoar, wind affect, and sun crust). Ski pen of up to 35cm in sheltered area means sluff management is still key in steep terrain. The snowpack below is mostly strong rounded crystals, with critical layers from earlier this winter now dormant.
