Avalanche Summary
Reports from Monday include two small skier triggered avalanches (both size 1). One was a wind slab on a northwest-facing slope under a wind lip and the other was a remotely triggered avalanche on a 50 cm deep surface hoar layer at 1000 m. These small avalanches may be indicators that the upper snowpack has settled into a more reactive slab.
Snowpack Summary
New snow is falling on a temperature crust left over from warm temperatures on the weekend. This crust likely exists well into the alpine. The warm temperatures also settled the upper snowpack, potentially forming a slab above buried weak layers in the top 50 cm of the snowpack. The potential weak layers include a few crusts and surface hoar layers that formed in early January and December. Recent reports suggest the snow is well bonded to most of these layers, but the recent settlement of the upper snowpack may have changed that.
