    This layer is well bridged by a strong mid and upper snowpack but could still be triggered from shallow or rocky terrain or by a large load.

Weather Forecast

Very cold clear weather to continue through the weekend.  A system coming in on Monday/Tuesday will moderate temperatures and bring some much needed snow.

Snowpack Summary

Surface facetting due to extremely cold temps. Hard mid-pack is providing bridging strength over the weak basal facet layer at tree line and above. Recent settlement below tree line has greatly improved travel. Reasonable ski conditions can be found in sheltered features at tree line and below.

Avalanche Summary

No avalanche patrol today.

Confidence

The weather pattern is stable on Thursday
