Comments
Just had time to snap a photo, so approx. measurements. ENE facing. Natural during yesterday's storm, light dusting of new snow over debris. Downed trees on exit road, so guessing wind triggered. Pretty much down to ground/early season snow layer. Propagated across entire small slope, crown 6" - 18", wrapping around a tree. Looks like a small, few inch, narrow pocket sluffed off and stepped down to persistent slab, wall-to-wall, to ground.
