The ancients liked to put the workshop off to one side of the camp. They didn't want sharp flint chips on the floor of their house. Still up on high ground but not the main living site. If you find drills/scrappers/tools then you are on the main site. Think about it... tools are in your garage but your bullets (projectile points) could be found most anywhere the hunting was good. Don't think about just modern water sources. Imagine what the land looked like 9000 years ago... before dams or major drainage of wetlands and the changing of the watersheds. Many good places have no visable water source today but may produce good rocks. That'll be yo honeyhole....

The rock hunting is about learning where to go but also timing. You gotta keep your eye on things and go after every rain if you can. Ain't no different than fishing... the more you go the more you will find... you walk your butt off you will find sites and rocks. Its about know-how, timing, percentages, and a little luck

Benny, that is a great field.. old stuff in there. A harpeth river come out of there that you won't find any better in the country. Wish we were walking that one right now.
