Other mistake: When Cloud Dancing and Daniel walk a wounded Sully to a clearing, we see a road with what looks like flattened black tents on either side, and Cloud Dancing tells them the Army must have attacked it; that's what is left of a reservation. When it's a modern transport road for everyday access, very poorly disguised as a reservation camp.
