In recent days 2 skier-triggered avalanches were reported having failed on the February 12th surface hoar. For more information, go to our Incident Report database. On Monday a few size 2-2.5 natural slab avalanches were observed on the Coquihalla. Explosives control in the Duffey Lake area produced avalanches of similar size.

Light snowfall on the Duffey and heavy snowfall on the Coquihalla has been redistributed into wind slabs at treeline and above. The new snowfall puts weak surface hoar buried on February 20th up to 70cm below the surface. Where it exists, the surface hoar will likely prolong the reactivity of the recently developed storm slab.On shaded slopes up to 60cm of snow may overlie surface hoar which was buried on February 12th. Most reports of this layer are coming from the Duffey Lake area where observations include whumfing and easy, sudden planar test results. On solar aspects and at lower elevations recent accumulations overlie a series of melt freeze crusts.The mid and lower snowpack pack layers are generally well settled.
