Macdonald's draw clear skies, temp in upper 30's. no wind
intentional ski cut at 200pm. wind blown slab, ESE aspect, 38-40 degree slope, El. 9000, crown:8"-24", 150' wide, 400 vert runout, new snow that ran on old surface hoar. also appeared to rip out a couple of deeper pockets a few feet wide and a foot deeper about half way down. The toe of avalanche hit berm above mcmansion
no initial collapse or cracks till I started the ski cut and all it took was a couple good bounces to get snow to crack and propagate wind deposit loading ESE, snow was still pretty fresh, a little wind swept and some warming of the snow
