Windslabs and wind effect

Skied at Jumbo on the 13th and 14th. There was strong NW winds on the 13th that unfortunately completely hammered all open slopes. Still great skiing in the trees (20cm ski pen), but anything exposed to wind was terrible. We remote triggered a size 1 windslab on the 13th on the crossloaded easterly slope at treeline (see photos), and another group had triggered a similar avalanche nearby. These appeared to be failing on the Jan 7th surface hoar which was size 6mm and down 20-30cm in sheltered areas. We also saw several naturals alpine and treeline, E aspects, up to size 2, which looked to be similar depth and were propagating far across features. Wouldn’t recommend heading to the alpine any time soon, but there's good tree skiing to be had.
