After some sledding and skiing in York Creek we were surprised to come across this freshly snowmobile triggered avalanche on an east aspect in a burn at 1900m. It was likely triggered by someone airing into this wind loaded, steep convex roll/ridge feature? (Let us know if you were there and know.) The propagation was impressive, the avalanche was over 100m wide. The crown was 60-100cm deep and the slab was made up of old stiff wind affected snow, and even some crusts. We are not seeing this kind of thing as a widespread problem right now, but it is good reminder that avalanches are still possible at moderate hazard in isolated terrain features like this big wind loaded convexity. Terrain traps like trees can worsen the consequences of an avalanche like this as well.

We saw no new natural avalanches today and the cold temperatures were keeping the new 15-20cm of storm snow dry.
