NEComments:
Both of these small, soft slabs were triggered by sluff on a ski cut. Crowns were about 30 cm (12"), very small pockets. This was a cross-loaded slope facing NE, the new snow ran on the old interface that was buried 04/10, which is a firm crust about 5 cm (2") thick. The new snow was very soft and light, even the wind-deposited snow did not indicate slab-like characteristics.Photo:
Signs of Unstable Snow

Observations
Heavy snow showers off and on all afternoon. The sun did poke out for an hour or so early afternoon, which was just enough to dampen the new snow on south faces. 20-25 cm (8-10") new snow in the parking lot. 35-45 cm (14-18") on ridgetops. The new snow was very low-density (less than 10%). Winds were out of the W/NW and easily moving around the new snow. Beneath the 04/10 interface was a mix of melt-freeze crusts from the late March warmup.
