That's what they look like in Seymour, Indiana too.

BTW, the entire area occupied by most of the town has been rendered flat. An ancient Indian council circle lies to the East.

Of course, another interpretation could be they were just cleaning up the yard and stacked the bags of rocks in a few convenient locations.

Those pesky aliens were clever.
