LOL!! My comment after yours mentions the book series, which I thoroughly enjoyed, plus the few movies starring Adam Beach and Wes Studi.
I love that part of the country and those books brought it back to me. Great stories and believable Navajo characters.
Wes Studi did a film called “The Only Good Indian”. It takes place in the early 20th Century and he’s a guy who tracks down Indian kids who have run away from the boarding schools. He wants the bounty, but he also wants to be accepted by whites so he can become the first Indian Pinkerton agent. Anyway, if you’ve got On Demand and you’re a Studi fan, check it out.
