We went up lakkit mountain. On the skin track up we had one large whoomph in an area where the snow was heavily sun affected and moist through the depth of the snowpack. We were unsure if the whoomphing was due to the temperature of the snowpack or due to a deep instability- so we dug a pit prior to our descent on the aspect we were planning to ski. When we dug our pit, we had snow depth of 1 m. The mid pack was pretty strong and seemed to be well bonded to the layers below. We saw a wind slab avalanche that had been triggered by a cornice collapse that was approx. 1 week old, and some more recent loose wet avalanches. The riding quality was variable: wet and heavy in sun affected areas and hard pack on the more north facing slopes that had not yet had much sun today. There was also new surface hoar forming on north facing slopes.

Snow conditions were: Wet, Hard. Weather conditions were: Warm, Sunny. Riding quality was ok.
