Our mid month wind event, torched the alpine, creating a pencil hard, wind pressed slab that will feel super bomber under our skis, board, or sled but is underlain with a sugary layer of near surface facets. In upper elevation, above treeline terrain we have moved this setup into a persistent weak layer or PWL category. I think you'd be hard pressed to trigger an avalanche today, but if you're getting after it on sustained, steep terrain in the alpine, I think to myself that even a small slide in consequential terrain could get rowdy if it strains me through rocks, cliffs, or trees.
Fortunately, we can steer clear of this problem today... lose the wind and you lose the problem. Simply lose some elevation and hone in on mid and upper elevation, wind sheltered terrain where you'll score a great day of cold, recycled powder riding and turning conditions.
