New snow continues to incrementally build over a crust. Keep an eye out for signs of instability, as you transition into open terrain in the alpine where wind slabs may linger.




Avalanche Summary

There were a few skier-triggered size 1 wind slab and dry loose avalanches reported from steep terrain on Tuesday. This MIN post is a great example of where the wind slab can still be triggered by riders.

Brief periods of sun, triggered natural and skier-controlled wet loose up to size 1.5 on Tuesday.

Snowpack Summary

Roughly 20 to 30 cm of recent snow has been incrementally building over a crust at treeline and alpine elevations. Lower elevation surface snow is likely moist or wet depending on recent freezing levels.

A layer of facets (and small surface hoar in some areas) is buried 30-60 cm deep and a layer of facets sitting on a crust is buried 80-100 cm deep. While previous warming and subsequent cooling have likely helped to strengthen these layers, we will continue to monitor them for signs of reactivity.
