I found this crown just after 10 and didn't notice distinct tracks leaving the crown or signs of anyone being caught (beacon in search detected nothing). Pile at the base was pretty small and pretty soft. Seemed most notable for having broken at the very sharp convex edge of the road cut even though the slope was not generally very steep, and for the very smooth sliding surface it exposed.
