Continuity mistake: When Adam introduces himself to Ted Hackett, the back-junction on Ted's Y-back braces is bunched up as he and Adam are walking through the doorway, but in the next interior shot of them entering the home, the Y-back is suddenly lying properly. (00:31:35)
Continuity mistake: It is obvious that a wind machine was used in the opening scene. Dust, straw and leaves are blowing across the Ponderosa and trees in the foreground are swaying but the trees in the background are motionless. Two minutes later, a shot of a cloud-filled sky and a flash of lightning is shown and rain starts falling. In the next shot, Joe is inside the barn and sunlight is streaming through the windows even though rain is falling. Joe's horse then gets spooked by a lightning bolt and knocks Joe to the ground. The horse tramples him several times but when Joe is finally able to get up, the back of his shirt and pants are completely clean.
Continuity mistake: When Lothario Larkin is visiting the girl he left at the altar, (Nancy I think) the scene opens, showing Lethario's carriage horse with a feed bag on.

Continuity mistake: Halfway through the show, Ben is talking to the commanding officer and captain of a fort.

When they walk to the door, it is closed.
Continuity mistake: A flashback episode set in the 1840s opens with Ben Cartwright as a first mate aboard a clipper ship. Rear-screen projection shows an ocean and a grey overcast sky. In a shot of the crew on the rigging and in the crow's nest, the sky is deep blue with a few white clouds.
Continuity mistake: Laura Dayton is at a party at the Ponderosa but leaves and goes outside because she has a headache. Ben Cartwright's brother Will comes out and says he'll take her home via horse and buggy. It is night and the sky is dark, but when they reach Laura's house, it appears to be early evening. The sky is much lighter and the trees are casting long shadows on the ground.
