Buried surface hoar is likely becoming harder to trigger. However, consequences remain high if triggered. Small avalanches have potential to step down to deeper layers.
Don't let the new snow draw you into big terrain, the snowpack remains generally shallow and weak.
Buried surface hoar is likely becoming harder to trigger. However, consequences remain high if triggered. Small avalanches have potential to step down to deeper layers.
A layer of weak facets near the ground can be triggered by large loads or even by riders in shallow rocky areas.
No recent avalanches have been reported. While avalanche activity has decreased avalanches remain possible which could have particularly high consequences.
If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
Recent snow continues to accumulate atop a complex, generally weak snowpack.
The mid and lower snowpack contain a number potentially problematic weak layers. Of particular note is a layer of surface hoar down roughly 40 to 80 cm from the surface.
Weak basal facets characterize the lower snowpack, especially in alpine terrain.
Snowpack depths at treeline range from 60 to 140 cm.
