Dry snow at upper elevations may remain reactive to rider triggers especially where it's been affected by wind.
Cool temperatures strengthen the snowpack but the status of buried weak layers remains uncertain.
Dry snow at upper elevations may remain reactive to rider triggers especially where it's been affected by wind.
Reactive weak layers buried in January-February are distributed sporadically through the region. We suspect the recent storm cycle may have wiped them out, especially at lower elevations, but we can't yet say for sure.
A widespread natural avalanche cycle occurred during the storm on the weekend including:
Numerous size 3 persistent slab avalanches at all elevations, but most at treeline. These are suspected to have run on the February crust layer.
Storm and wind slabs size 2-3, on northeast to southeast aspects at alpine and treeline elevations.
10-20 cm of dry snow accumulates over a wind-sculpted landscape and crust below ~1700 m.
A few layers buried between late January and mid February, consisting of surface hoar, facets, and/or crust, are buried roughly 100 to 150 cm below the surface. We suspect the recent storm cycle may have wiped them out, especially at low elevations, but we can't yet rule them out with any certainty.
The remainder of the snowpack is well consolidated, with no other significant layers of concern.
