Sunny South York

Today in the York Creek area of the Crowsnest Pass we found an extremely wind affected surface of hard wind pressed snow mixed with sustrugi. The new wind slabs formed from Thursday's strong SW winds are bonding to previous surfaces. On solar slopes the hard slab was becoming moist, but the light to moderate SW wind was slowing the warming. The top 10 to 15 cm were becoming moist on slopes impacted by the sun, and more pronounced below 1500 m. We did not observe any new avalanche activity, but we did get a reactive test in our snow profile down 70 cm where the consolidated upper snowpack is not bonding to the facets formed during the cold temperatures of late January. This continues to indicate potential for propagation (slab avalanches).
