Observation: Chugach State Park

A widely variable snowpack structure exists. Instabilities were snowpack and aspect dependent today. Snowpack ranged from poor structure (5 lemons) to good (0 lemons) frequently within 60 yards. Poor structure was often in shallower areas HS<120cm and had depth hoar sometimes chained (photo). These areas whumphing was common although the resulting cracking was small, <10m radius. Fresh wind slab was reactive 10-30cm thick on top of 20200321 HST which has already faceted (see pic of ASa D1). Solar aspects began a roller ball cycle with a few Wet Loose D1 in the afternoon and the snow surface became moist.
