Avalanche Summary

There is no recent avalanche activity to report.

If you do go into the backcountry, consider submitting a Mountain Information Network report.

Snowpack Summary

Storm snow from last week has been redistributed into alpine and treeline lee terrain by predominantly southerly wind. Below 1200 meter elevation, a thick crust is present approximately 50 cm above the ground. The middle and lower snowpack is reported to be well settled and bonded. Snow depth varies from 75-200 cm depending on the aspect,
