There was an area than had tons of chips of flint on the ground never seen any of them that look like they were work on . It was next to a spring feed creek that would make a perfect camping area . Couldn't figure it out
I was duck hunting there and notice it when I was walking back to my jeep . Plan on going back and checking it out but its on Corp land and that means no digging
Go to the corp of engineers office they will give you a permit for free. I just got one I'm down I'm Dallas area. I hunt and dig corp land all the time just follow their rules and they never mess with you
