Rockin' thru the Rockies is the 45th short subject starring American slapstick comedy team The Three Stooges. The trio made a total of 190 shorts for Columbia Pictures between 1934 and 1959.
The Stooges are guides (circa late 1800s), who are helping a trio christened "Nell's Belles" travel across the Rocky Mountains to San Francisco, the location of their next performance. While preparing some corned beef, a group of Indians urges them to get off their land as soon as possible. Since Curly scared off the horses earlier, the group are stuck there for the night. Unfortunately, snow falls while they sleep. They awake to discover a bear has devoured their food supply, so the three hapless guides try unsuccessfully to catch some fish in a nearby frozen lake. The fishing expedition is interrupted by Nell (Kathryn Sheldon), who discovers the Belles — Lorna Gray, Dorothy Appleby and Linda Winters — have been kidnapped by the Indians. The Belles manage to escape, and the troupe leaves the Indians' land quickly.
- The title of this film is often mistaken for the 1945 the Stooges feature film Rockin' in the Rockies.
- After the snow collapses the tent-like structure from the set of "Uncle Tom's Cabin" (in which the troupe performs in a traveling show), Curly falls through a curtain, lands on the girls in bed, and says, "The walls of Jericho collapsed." This is a reference to a scene in Columbia's It Happened One Night, where the flimsy barricade set up between Claudette Colbert and Clark Gable in a motor lodge was called the "walls of Jericho."
- The conclusion of this film is reminiscent of Early American folklore as the Stooges leave Indian territory a la Windwagon Smith.
