Avalanche Summary

On Wednesday there were reports of small dry loose avalanches. No slabs were reported.

A skier triggered a small wind slab on Tuesday, on a north aspect at treeline.

Data is very limited in this region. Please submit a report on the Mountain Information Network. Even a simple photo is a huge help to other backcountry users.

Snowpack Summary

In sheltered spots up to 30 cm of snow is sitting on a melt-freeze crust from early December. At upper elevations, wind has redistributed snow to lee features.

In some areas, freezing rain has been reported on top of the new snow creating a crust. As well as surface hoar that was buried yesterday.

There are no deeper layers of concern.

Data is very limited in this region.
