Continuity mistake: In the opening sequence, when the stagecoach first overturns, only one wheel is left spinning. In the next shot, as the comancheros ride up to the wreckage, all four wheels are spinning.
Plot hole: Victoria asks her rescuers to take her to Rancho Velásquez. When they ask where it is, she says, "About 30 miles from here." Though she never indicates a direction, they reply, "Sorry, we're not going that way." (00:23:20)
Continuity mistake: Manolito is bitten on the right ankle by a rattlesnake. But when Maria is later adjusting his bandage, she doctors his left leg instead. (00:01:10 - 00:09:15)
Continuity mistake: When the bad guys arrive in Nevermore, they prejudicially assume that Victoria is Manolito's wife. No one disabuses them of this notion, yet John later tells one of them that he was right about Victoria being his wife. (00:30:30)
Continuity mistake: The leather strap around Manolito's neck is sticking prominently up out of his shirt collar in all the over-the-shoulder shots, but it disappears every time the angle reverses to a frontal view. (00:36:00)
Continuity mistake: When Buck and Blue are playing their game on the tree stump, Buck's left hand is down at his side in one shot, then instantly tucked up under his chin in the next.
Continuity mistake: When the gunman shoots at Mano and Ebenezer from the upstairs window, Mano shoots back and hits him. We see the man fall back away from the window into the room. Yet in the next shot, he somehow reverses directions and falls forward instead, breaking through the glass and falling out onto the roof.
Factual error: Ramon's six-gun fires more than a dozen times without ever being reloaded. (00:37:00)
A Man to Match the Land - S4-E17
Continuity mistake: Red Eagle's war paint changes between takes. Sometimes it's red with blue striping. In other shots, the blue stripes disappear.
Continuity mistake: Charly steps forward several feet before pointing her gun and shooting the hats off two cowboys on the boardwalk. But in the very next shot, she's suddenly standing back beside Buck, without time to get there. (00:08:00)
Factual error: Though High Chaparral had a windmill and a water tower, there were no pipes to deliver water to the house - just a well that appeared in the yard only when called for in the script. They had plenty of eggs, but no chicken coops, and though Victoria always had fresh flowers in the house, we never saw a garden. We also never saw the ranch outhouse, but no surprise there: no one on TV in the 60s ever had a bathroom.
Revealing mistake: When Buck gallops away from Mano and the newly-rescued Sarah, two jet contrails are visible in the sky at the upper left of the screen.
The Last Hundred Miles - S2-E17
Continuity mistake: When John speaks to Cochise, two Apache warriors standing behind him change both their poses and their distance from John every time the camera angle reverses. (00:23:30)
Continuity mistake: While Buck and Mano are chasing the Apaches, Mano's mount changes from a horse with a blond mane and tail to one with an all-brown mane and tail and back again.
Factual error: In the final battle with the Apaches, Blue and most of the rest of the Chaparral men fire their 6-shooters dozens of times without ever reloading.
The Stallion - S2-E1
Continuity mistake: While the black stallion prances in the corral, a bridle appears on his head, even though no one's gone near him.
Continuity mistake: When John confronts Joe about firing Jelks, Joe's hands change positions, from down at his sides to up at chest level adjusting his gloves, every time the camera angle changes. (00:22:50)
Apache Trust - S3-E8
Plot hole: Somewhere in old Tucson, there must have been a merchant with dozens of identical hats to sell. Here, as in other episodes, Blue's hat is lost somewhere in the desert when he's captured by the Apaches. By the next episode, though, he has it (or one just like it) back again. Lost horses, sometimes even after being killed, had a similar habit of reappearing alive and well in the following week's episode. (00:44:40)
Continuity mistake: At the end, Sarah leaps onto a horse, jumps the fence and rejoins the waiting Apaches. On the way, in between shots, her long green dress, which has been bunched up beneath her during the fence leap, neatly rearranges itself and drapes quite prettily over the horse on all sides, even though she hasn't had time to touch it.
For What We Are About to Receive - S2-E11
Continuity mistake: When Perlita opens her door to Manolito, there's a wooden bench just outside that wasn't there in the previous exterior shot of Mano approaching the door. When he leaves, it's gone again.
