Bloopers galore Other reviewers have pointed out the cultural and historical mistakes rightfully. But I would like to point out the modern ones. The main character stays in a spacious lodge for one. She leaves, including for a trip of a week, without turning off the lights, locking the door, or even putting out the unneeded fire in the fireplace.
She and the park ranger never wear a hat for protection against the sun. They have no canteens of water or are seen staying hydrated. If I were going out in the wilderness for a week, I would charge up my cellphone, spotty reception or not. She did use it to take pictures with.
She also told the ranger she was taking only a few power bars for food. It also might have seemed more authentic to have at least a few Native American cast members as extras.
The inside of the grandmother's house looked like a modern suburban house. Many Native Americans living in rural isolation have a jerry-built home or an old trailer house. These are just a few thoughts off the top of my head. The scenery was the bet part.
