Observations are limited this time of year. Be sure to verify conditions as you go.

If you are getting out in the backcountry, consider sharing your observations on the Mountain Information Network (MIN)!

Snowpack Summary

The upper snowpack is mostly hard and sculpted by the wind at alpine elevations and deep into the treeline, with only the most sheltered areas holding soft snow.

Cold temperatures continue to facet the mid and lower snowpack.

An average snowpack depth of around 100 cm bu this varies significantly in areas affected by the wind.
