Revealing mistake: When Rex interrupts the poker game, the camera pulls in for a close-up of the lantern - so close that we can see it's illuminated by a big round light bulb.
The Rex Montana Story - S1-E35
Visible crew/equipment: During Flint's observation of the pow-wow, tire tracks from the camera truck are visible in the background.
Factual error: In the first minute of the episode, there is a herd of wildebeest shown instead of bison, entirely wrong for the area. (00:01:00)
The Ruth Marshall Story - S3-E13

Factual error: The characters visit Aurora, Colorado. The series takes place in 1860s-1870s - at the time it was named Fletcher. (00:06:25)
Factual error: The wagon master is sitting drinking a cup of coffee, and he has two bandaids on the first and second finger of his hand. Bandaids were not introduced until the 1920's.
Revealing mistake: When Jan Clayton picks up the baby to go outside and torch the wagon, she swings the baby around carelessly, revealing the shiny (and unsettling) head of an old prop baby doll. (00:37:15)

Factual error: At an 1868 church service, Mark sings "How Great Thou Art." While the tune of this hymn is 19th Century, the English lyrics he's singing weren't composed until the 1920s.
Other mistake: As the 2 buffaloes are walking out of the scene at the top of the hill Charlie says to Clyde that 'it's either gonna be her or me' but as both buffaloes' bellies are exposed in the same shot, it's clear that both buffaloes are males, or bulls.
The Frank Carter Story - S5-E34
Continuity mistake: At the end of the episode, Duke is riding back to wagon train and has a gun holster on his left side. However, when he rides into camp the gun holster has switched to the right side. (00:48:00 - 00:49:00)
