Outflow winds have extensively affected the snow surface. This makes riding snowmobiles challenging, but we bet you could still find some chalky ski turns.
Today we avoided steep, convex south-facing features where stiff wind slabs exist. We saw evidence of older wind slabs which happened naturally over the weekend on steep, south-facing gully features.
We dug to investigate the persistent weak layer and while we didn't get any results in Extended Column Tests we did get a propagating result in a Propagation Saw Test. The layer is 95 cm deep at 1200 m in the Fraser Chutes area. While reactivity on this layer does appear to be decreasing, we are still avoiding shallow, and thin-to-thick start zones where the layer would be easier to trigger. There is also the potential that a wind slab avalanche could step down to trigger this layer.
