15 to 25 cm of snow overlies a weak layer of small surface hoar in sheltered areas and/or a thin sun crust on solar aspects. This has been reactive to human triggering.
New snow and wind have formed slabs that may be reactive to human triggers, especially where buried surface hoar or a crust exists.
Minimize exposure to steep, sun-exposed slopes.
15 to 25 cm of snow overlies a weak layer of small surface hoar in sheltered areas and/or a thin sun crust on solar aspects. This has been reactive to human triggering.
Expect sunshine to trigger wet loose avalanches on steep slopes facing the sun.
Natural avalanche activity has tapered but numerous rider-triggered and remote helicopter-triggered avalanches have been reported up to size 2.5. Some of these avalanches are failing on buried sun crust and surface hoar down 20-25 cm deep.
A new sun crust likely exists on steep solar aspects. 15 to 25 cm of snow overlies a variety of surfaces including a weak layer of small surface hoar in sheltered areas and/or a thin sun crust on solar aspects.
The widespread crust buried in early February is down 30 to 50 cm.
Various weak layers persist in the mid to lower snowpack, however, triggering these layers is unlikely where they are capped by a thick crust.
