Graves Mountain Pit Mine.

Graves Mountain was a small collection of three hills in Eastern Georgia where Tiffany sourced the rutile for their jewelry and NASA sourced the kyanite for the Space Shuttle heat shield tiles. The hills have been flattened, and the mine closed, but rock hounds still come from all over on the two weekends a year it's open to the public for digging. It has a kind of Southwestern US feel, and if you look at the cliffs with the right eyes you can catch echoes of Georgia O'Keefe, but mostly the only echoes are from hammers and chisels.
