Avalanche Summary
No new avalanches have been reported. There are very few field observations coming from this forecast area. Remember that a lack of avalanche reports does not necessarily mean a lack of avalanche activity.
If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
Snowpack Summary
Snowpack has been heavily wind-affected in exposed terrain. A layer of surface hoar is roughly 10 to 30 cm below the surface.
In general, the snowpack is still very shallow and facetted. Average snowpack depths vary dramatically at treeline from 20 to 80 cm.
