Highlights

Natural avalanche activity has slowed down. The consequences of triggering the basal facets are still high. Be mindful in route selection.

    The basal facets are impressive, take the time to dig a pit. This layer will be very distinctive.

Avalanche Summary

No new avalanches were observed today.

Snowpack Summary

The most recent snowfall left us with about 10cm of snow. This new snow overlies the Jan. 17 SH which is mostly found below tree line(below 2200m) and will be on our radar again when we get more snow. This new snow has been touched by the wind in the alpine in places but skies nicely once it becomes sheltered.We dug in a few different places today and got varying results. The thin areas are more reactive to test results on the basal facets than the deeper places. In the Commonwealth area today we dug a pit with a depth of 80cm and the bottom half was facets. That said, we have had a lot of wind on the slopes this winter, so it is challenging to know where the thin and deeper areas are. Triggering an avalanche from a thin spot has a high likelihood to spread across the slope.
