I woke up early and went to ski a NE aspect of Abe’s armchair and found soft snow in trees from 7400 to the summit there are obvious signs of wind loading (pillowing)from the summit to about 9700 I didn’t experience any slabs, collapsing or whumps. HoweverI kept my skiing conservative at upper elevations just in case. I didn’t witness any avalanches except only some sluffing of dry snow at lower elevations on steeper terrain.
I looked at Vienna peak and it looks very wind loaded from summit to base. See picture
