This problem lingers where a hard slab overlies a layer of weak, sugary faceted crystals on top of a thick crust.
Low danger does not mean no avalanches.
Avoid areas where a small avalanche could drag you into cliffs, trees, rocks, etc and increase the consequence.

No new avalanches were reported at the time of publishing on Monday.
On Sunday, southwest of Mcbride a small (size 1.5) wind slab was remotely triggered from 5 metres away with no involvement.
On Saturday, there were numerous small wet loose avalanches from slopes exposed to the sun and a couple of small rider-controlled wind slabs.
In treeline terrain that is sheltered from the wind, 15 to 25 cm of settled snow sits above the crust.
South through west aspects are likely stripped down to a thick crust that formed early in February. In general, the crust is strong and supportive to travel below 1900 m. Above 1900 m the crust becomes breakable and tapers out around 2400 m.
On north through east aspects you will likely find old wind slabs on sugary facets over this crust.
