Continuously assess for wind slabs as you transition into exposed terrain.
Rider triggerable wind slabs will likely still be found near ridge crests.
wind slabs will likely still be found on north and east facing terrain at treeline and above. Expect the most reactive slabs in immediate lee terrain, such as just below ridge tops.
No new avalanches have been reported in a few days.
A notable persistent slab avalanche (size 3) was reported on Monday. This avalanche was naturally triggered on a north-east alpine slope near Clemina Creek. This very large avalanche ran in a path that does not commonly run, and is suspected to have stepped down to the November crust.
Up to 30 cm of recent storm snow has been redistributed by south through northwest wind at treeline and above.
40 to 80 cm of well-settled storm snow overlies a prominent crust formed in mid-December that extends up to 2200 m.
Where the crust is thick and supportive, it effectively caps a few of the mid-snowpack instabilities, making them difficult to trigger. These include a spotty surface hoar layer from early December and a crust/facet layer from mid-November. These layers may still be a concern in the high alpine, where the crust is thin or nonexistent.
