Snowpack Observations

Storm slab is the primary problem above 6400'. Dense new snow overlays low density faceted snow from the past week on some aspects and sun crust on other aspects. Slabs were easily triggered on slopes over 35º. Touchiness will likely increase with continued loading.
Below 6400' rain is saturating the snowpack. No loose wet or wet slab were observed today.

Terrain Use

We stayed on slopes under 30º today.
