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

Confidence

Moderate - Uncertainty is due to extremely variable snowpack conditions reported through the region.

Snowpack Summary

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.
