jrebel, Hope all is well. I was born in North East Oklahoma. A lot of burried gold in your area. I would get volume 8 of the atlasses:
treasure atlas, Maps, Atlases, Globes, Nonfiction Books items on eBay.com
Can you and oneguyfromohio provide County you want info, looked for river emptying into Erie, many, many stories in both of your areas.
Something you could do for fun? is goto geocashing.com, register, then click "hide or seek treasure". click "seek", enter your zip code, and it will list things hid in your area. You will be given GPS coordinates, and a clue that needs to be decyphered, Easy to decypher with the conversion also on page, kids can do it. You are suppose to look with your GPS. I have been a little lazy, and will copy and paste coordinates to Google Earth. In the US, the coordinates will be North lattitudes and West Longitudes, example, I live near N25.000.000, W 80.000.000. So After I copy and paste to google earth, I delete the N and the W, and add a - to west longitudes. Example for me, it would be 25.000.000, -80.000.000, then goto that coordinate, and zoom in. Lazy way to look for the treasure with no GPS.
Will dig up more info. So many stories, so little time. Take Care
