A size 2 skier-triggered avalanche was reported in the Duffey Lake area on Friday. It was triggered on a NE facing alpine slope and is suspected to have failed on the late March sun crust. There have also been reports of isolated natural slab avalanches to size 2.5, primarily on solar aspects during the afternoon. Loose wet activity continues on steep solar aspects.

The snow surface consists of old wind slabs in exposed alpine terrain, spotty surface hoar on shady slopes, and a sun crust/moist snow on solar aspects. This sits on up to a metre of settling storm snow from last week. The March 27 layer is predominately a crusty interface except on north facing slopes at treeline and above where small surface hoar (5mm) may be found. It's now down 60-120 cm and has recently exhibited hard, sudden results and a Rutschblock 4 whole block failure in the Duffey Lake area. Deep persistent weaknesses linger in many colder and shallower snowpack areas. Daytime warming and sun-exposure may cause surface snow to lose cohesion and cornices to weaken.
