Avalanche Summary
Windslabs to size 1.5 were skier triggered on steep, north facing slopes in the north of the region on Saturday. They were reported to have ran on surface hoar buried on March 9th. .
Snowpack Summary
A dusting of new snow overlies a variety of old surfaces which include: a crust at lower elevations and on solar aspects, faceted powder on shaded slopes, and surface hoar. The surface hoar, which was reported from the north of the region, has already been reactive in spots where it was buried by thin wind slabs formed by strong southwest winds on Saturday.Between 50 and 80cm below the surface is a layer surface hoar which was buried on February 20th. Although this layer has a history of producing large avalanches, triggering this layer has now become difficult, and would most likely require a very large trigger on a steep, unsupported slope.Below this the snowpack is generally well settled and strong.
