Bottom Line: Spring weather can be highly variable and create a mix of avalanche problems to watch out for. Snow conditions and snow stability can change drastically from day to day or hour to hour. Anticipate rapid change and plan accordingly. Plenty of snowfall over the winter with more spring snow to come makes avalanches possible into summer.

The Last Word

We ended our 35th winter in operation after 141 forecasts and ZERO avalanche fatalities, the second winter in a row with no avalanche deaths. The last time this happened was 1988 and 1989. It’s been an incredible season. 

Thank you for all your support! Our success is directly related to support from our community and the Forest Service. Thanks to the readers of the forecast, everyone that sent in observations, took an avalanche class, or donated money, time or gear.  Have a safe spring and summer!
