Blackcomb Backcountry

Skied around Pattison+Decker. Dug down near the NW face of Pattison and found two distinct wind slab layers 10cm and 25cm down. The top layer popped easily and the second popped planarly CTM20. Large crust 45 down that seems well bonded to the snow above it. Variable conditions on the rest of the day. Some sheltered powder, lots of evidenxe of wind transport, and a crust forming on solar aspects. Ridges are windscoured and cornices were loomin large. Crusty and moist back in treeline Temps were -5 to -10 in the alpine, mostly clear skies and low to moderate wind throughout the day.
