Along the north side of the Sudbury Rd. in Weston, there are some conservation land accesses, mixed in with forbidding looking driveways ("Armed Guard"). Last weekend I eaked out two rock piles from the area, although I know I have found other piles in there in the past.
I am fascinated by the fact that piles continue to exist in the modern suburbs. The case in point shows that, really, they barely do. Weston has a high population density.
In the first picture above, a single pile occurs in a slight gully. It could almost be a crossed pair. This was actually south of the road. In the second picture, a large and a small rock-on-rock occur at a bit of a wet place. That was north of the road.
