Asulkan wind slabs

Our party spent three days in the Asulkan valley (Feb 2-4). Feb 2: rode tree triangle in very deep powder, no instabilities noted, but a party commented on rider-triggered storm slab on the mushroom people run. Feb 3: rode in the Asulkan glacier (probed 2.15 to 2.5 m to the ice) for the day, great deep powder, no instabilities noted but we rode conservative lines from the Asulkan col ridge. Feb 4: the wind was strong overnight, and created stiff wind slabs above the hut. On our approach to the Young´s headwall our party remotely triggered a sz 1.5 wind slab on an unsupported steep convex roll, NW aspect. No involvement. We rode back to the hut and skied out without incidence but ski quality was poor due to widespread wind slabs. Below the hut snow remained cold, unaffected by the wind and no instabilities noted. -15C the the car.
