Hartleyhenge
Calvander, North Carolina
A Druid-looking arrangement of rocks and monolithic slabs stands in a grassy field. It's officially named "Stone Knoll," but locals call it Hartleyhenge for its builder, the late John Hartley. He trucked in the stones from a quarry in Tennessee and didn't mind if people climbed on them.
Hartley built subdivisions for a living, and often set aside spaces for labyrinths and other consciousness-expanding rock arrangements. He placed the mysterious Hartleyhenge stones in a kind of spiral, oriented the monoliths on the points of the compass, and bolted bronze plaques to the rocks featuring animal symbols and poems, apparently written by himself.
Hartleyhenge was Hartley's biggest foray into neolithic rock architecture. He died in 2011, never revealing what it meant.
