Terrain sheltered from the wind will have the best and safest riding.
Wind slab formation has been relatively constant, and slabs have been consistently reactive to human-triggering on the west slope of the region.
On Friday, explosives control targeting buried weak layers with large explosives triggered one large (size 2.5) persistent slab near Pine Pass. This occurred on a south aspect at treeline.
On Thursday, there were several dry loose avalanches.
Up to about 40 cm of snow since March 7 overlies wind-affected old surfaces in the alpine and a crust that extends to ridgetop. Wind slab formation from easterly winds occurred with the earlier storm, now buried by either low density snow or more westerly wind transport. The crust becomes supportive at lower elevations and is 5 cm thick below 1400 m.
Another crust with faceted snow above, buried at treeline and below in February, is found around 100 to 160 cm deep. It's becoming well bonded to the surrounding snow and at lower elevations will be capped by more recent crust.
The remainder of the snowpack is well consolidated with no other layers of concern.
