Small loose avalanches remain a concern on steep terrain.
Shallow rocky areas should still be considered suspect.
Warm temperatures may create wet loose avalanches on steep south-facing slopes. Keep in mind, that wet loose avalanches may start small, but they can grow and push you into dangerous terrain.
Numerous wet loose avalanches occurred Tuesday and Wednesday on south aspects throughout the region, as conditions were clear and sunny.
Few natural dry loose avalanches (size 1) were released within the light snow from steep alpine terrain over the weekend.
A slab avalanche (size 1.5) was triggered by a snowmobiler near York Creek on Friday on a short but steep northerly slope below treeline.

The region has received 20-25 cm of recent snow since Saturday, which has settled quickly into moist snow at most elevations. This overlies a crust on solar aspects and faceted snow in shaded and wind-sheltered areas. Wind-affected surfaces are also found in exposed areas. At lower elevations, a crust exists near the surface.
A melt-freeze crust with facets above can be found 50 to 120 cm deep, but it has not produced any recent avalanche activity in the region.
The weak layer at the base of the snowpack produced some large avalanches, with strong sun and warm temperatures in the neighbouring region of Kananaskis. Professionals are still tracking it to watch for signs of it waking up in the South Rockies region.
The region will be under a building ridge of high pressure, with calm and dry conditions until Friday, when a southwesterly flow will return.
