Wind slabs remain possible to human-trigger.
Continually assess the surface snow as you travel and back off slopes that feel dense or stiff.
Loose snow will be impacted by wind in open areas. Check for wind slabs in steep and convex slopes at higher elevations or where new snow covers surface hoar.
Use extra caution in areas with a thin, uniform snowpack (less than 100 cm). These areas are inherently weak, with heavily faceted snow and crusts closer to the surface, making them easier to trigger.
On Tuesday a several size 1 human triggered wind slab avalanche was reported.
As storm snow settles over a surface hoar layer we expect human triggered avalanches to remain possible.
Up to 30 cm of recent accumulated storm snow covers a variety of old surfaces, including surface hoar in wind-sheltered terrain and a sun crust on steep south-facing slopes.
In the mid-snowpack, a melt-freeze crust exists that was buried in mid-December. This layer is most prevalent at treeline elevations and below.
The lower snowpack consists of a thick melt-freeze crust, with weak faceted snow and/or depth hoar near the ground in areas.
Snow depths vary widely across the region, averaging roughly 100 to 200 cm at treeline.
