Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Warm, 48 degrees at the parking lot around 3:00. Mostly cloudy.

Snow surface

Highly varying. Sun affected activity on sun facing slopes with lots of large roller balls in some areas. Melt freeze crust from somewhat firm to rock hard on a lot of the surface. Fairly recent slides on all aspects.


Slope aspect 32 degrees. It was warm with intermittent sun. We dug pits and observed a suncrust ~2 inches thick over a looser layer of facets, followed by another hard layer over another loose layer. We performed 3 ECTs, the first and third with full propagation and shearing at 22 and 18 hits at the deeper facets, over a foot deep. The second test failed with less cohesiveness at the shallower layer, though we determined those results obscured by a boulder. There were varying conditions all over the area, with fairly recent slides on all areas.
