Goofs

When Jim dances with the tavern girl, he holds his rifle butt up, but in the very next shot at the bar, he is holding the rifle muzzle up.

In the jail cell, Zeb has his knife. When Jim and Boone are led into the cell, the jailer says they can have their guns back when they pay their fine and get out. It would follow that a knife would've been surrendered also.

During the battle with the Crow, when Boone and Zeb fire their flintlocks, their frizzens are already forward in a fired position. In order to fire a flintlock, the frizzen needs to be back and covering the flash-pan. That way, when the trigger is pulled, the cock springs forward, strikes the frizzen and exposes the powder. At the same time, as the cock continues forward the flint sparks against the frizzen and drops sparks into the flash-plan. There, the powder ignites, sends a flash through the touch-hole, and ignites the main charge (propelling the bullet down and out of the barrel). BUT if the frizzen is already forward, the cock cannot strike sparks (and ignite the powder in the pan). Therefore, when the triggers on these weapons were pulled, the cock merely spring forward and struck nothing, meaning that these weapons could NOT fire.

Story takes place in 1832. In the distance automobiles are visible during the prologue.

As Jim and Boone approach St. Louis, Zeb, narrating, says they saw the town across the Missouri River. St. Louis is on the Mississippi River, and Jim and Boone, coming from Kentucky, would have seen it directly from the east side of that river.

Jim expresses amazement at the size of St. Louis. However, he had just come from Louisville, which in 1832 was about twice the size of St. Louis, so it should not have been a source of such astonishment.
