A phase III mitigation in Canton, Georgia (9CK9) did have a number of crystal
fragments if i recall. It was a multi component site from Paleo up to
Cherokee and colonial. The size of the site was vast, with 5000+ features.
I'm just a shovel bum so i cant get too technical here. ;] The mitigation
took place during the summer of 1995 by Garrow and Associates.
