Facets and/or surface hoar buried 50 to 80 cm deep is most prominent on north-facing slopes. Avoid areas with a thin or variable (thin to thick) snowpack.
Reactivity of buried weak layers is uncertain. Avoid large, open features capable of producing large avalanches and watch for signs of instability as you travel.
Facets and/or surface hoar buried 50 to 80 cm deep is most prominent on north-facing slopes. Avoid areas with a thin or variable (thin to thick) snowpack.
There has been no new avalanche activity reported in the last few days.
If you head into the backcountry, please consider posting a MIN report with photos and/or observations from your day.
10 to 30 cm of recent new snow has buried a widespread layer of surface hoar, which overlies crust on solar aspects and at low elevations.
A layer of facets, surface hoar and/or a crust buried in mid February is 30 to 50 cm below the snow surface and has been reactive in snowpack tests.
Deeper in the snowpack, a weak layer of facets and a crust from early December can be found. This layer appears to be dormant but is still worth keeping in mind in thin snowpack areas in the alpine.
