Recent snow has been most reactive in wind-loaded terrain features such as below ridge crests and roll-overs.
Expect deeper and more reactive slabs in wind-loaded terrain features. Be ready dial back your terrain choices if freezing levels start to rise above treeline.
Recent snow has been most reactive in wind-loaded terrain features such as below ridge crests and roll-overs.
30-50 cm of recent snow sits over a layer of facets and has been slow to bond. This layer may become more reactive with warming temperatures this weekend.
Storm slabs were reactive earlier in the week, with numerous natural, human- and remote-triggered avalanches up to size 2. On Wednesday, avalanche activity became more specific to wind-loaded features, with several naturals up to size 2.5 on north to east aspects in the alpine and upper treeline elevations.
30-50 cm of recent snow sits over a layer of facets formed during the early January cold snap. At upper elevations, the recent snow has seen some redistribution by wind. At lower elevations, a thin crust or moist snow may be found at the surface.
Old layers of surface hoar and crusts in the mid snowpack appear to be healing. The mid and lower snowpack is generally strong and well bonded.
