I found this on a trip to Turlingua Texas, on the big bend ranch. It was just on the edge of an old creek bed. I can only imagine why it was there, perhaps some indian was skinning an animal or something next to the creek and left it there. I had no idea what it was at first, i just saw the edge of it sticking out of the ground and thought the rock was a cool color, it wasn't until i washed it off several hours later that i realized what it was! Anyone know what kind of indians it could be from or anything else about it? I really dont know a lot about the western tribes and their history!
