Thanks guys. It seems like the Hopewell people quarried the finest gem grade materials off the ridge, those guys knew where to find the good stuff.
Tn., I think the Hopewell culture was around 1000 years or more(mid to late woodland) before the Dallas culture from Tn. and Va., just my best guess I may be off. Apparently the Dallas people moved from nw Tn. into areas of sw Va. There are many mounds in that area and alot of really interesting artifacts like shell masks, gorgets, and effigies that were attributed to the Dallas culture there. If you're ever in the Clinch valley area of Va. I highly recommend the museum in Saltville. It's small but packed with outstanding local artifacts, pre Clovis - historic, they have some fine Dallas phase exhibits.
