Hi Mag & Lotus. There were many indian tribes in this area over the last 10,000 years. Some of the arrowheads may date back that far.
The Choctaw Nation was huge here and is still here. Another tribe I think was Pawnee.
Other than that I'm not sure of any specefic tribes.
We are just a few miles from the Red River, and we have a nice creek that runs year round. They always camped close to the water source.
Mom has found many arrowheads around our little 38 acres.
We just had a huge rainfall with over 11 inches falling in some areas. The runoff carries a lot of rock and other stuff down to the creeks, so I'm not reall sure if the arrowheads that I'm finding in the creek were lost around here or somewhere upstream.
