Visible crew/equipment: When the young lady is trying to drag her dead husband away to bury him, as she takes a hold of the blanket you can see the covered wagon in the background and someone's legs behind the wheel begin to move to the right. She was suppose to be alone except for her dead husband. (00:34:00)
Factual error: The movie takes place in the early 1850's, referencing the rumor of gold in California. The girl, while rummaging through the wagon, comes across a pair of boots with zippers up the sides, zippers that wouldn't be invented for another 50 years.
