Most of the forecast area received a healthy dose of sunshine last Saturday. That sun quickly created a small crust on solar aspects. Even though the crust is thin and breakable it's proving to be a good slide surface for the new snow that fell on top of it.  We've had some reports of new snow avalanches happening on that crust. The best chance to trigger a avalanche on that crust would be on E-S-W facing, snow loaded slopes, above treeline.

The concern for buried persistent layers still exists. We haven't seen or heard of any avalanches going deep on those layers but it's still a possibility. Even though those layers aren't reactive right now...they're still there and worth noting.  Pay more attention to them if we see a rapid warm up in the future.

Daylight savings is this weekend! I can't believe it's already here. Winter seems to be hanging on for now, but look for spring to show up with full force by the weekend. With spring comes big changes in the snowpack. Be ready for a different types of avalanche problems starting this weekend.

Disclaimer

Avalanche conditions change for better or worse continually. Backcountry travelers should be prepared to assess current conditions for themselves, plan their routes of travel accordingly, and never travel alone. Backcountry travelers can reduce their exposure to avalanche hazards by utilizing timbered trails and ridge routes and by avoiding open and exposed terrain with slope angles of 30 degrees or more. Backcountry travelers should carry the necessary avalanche rescue equipment such as a shovel, avalanche probe or probe ski poles, a rescue beacon and a well-equipped first aid kit.  For a recorded version of the Avalanche Advisory call (208)765-7323.
