Although the likelihood of triggering has reduced, weak layers near the base of the snowpack remain a concern in steep rocky terrain.

TUESDAY: Scattered flurries, accumulation 5 cm, moderate west wind, alpine high temperature -6 C.

On Sunday there was a report of a size 3 explosives controlled deep persistent slab avalanche on a north aspect in the alpine. The fracture was 150 cm deep.

On Saturday there were reports loose dry avalanches to size 1.5 primarily on north aspects in the alpine.

So far this season's snowpack has a high degree of variability. Anywhere from 10 to 35 cm of snow may sit on a weak layer of surface hoar in sheltered areas at treeline. A second layer of surface hoar primarily found in the in north of the region is found 40-60 cm below the surface in sheltered areas at treeline.

There are a variety of crusts buried in the mid to lower snowpack. These crusts have mostly broken down. The base of the snowpack generally consists of facets and depth hoar.
