The working title for this film was Northwest Patrol. Although the opening title card of the print viewed read: "Interstate Television Corporation presents James Oliver Curwood's Northwest Territory," no Curwood novel or story by that name has been discovered, and it is possible that the story for this film was merely suggested by his popular stories about North West Mounted Police. The title card on the print viewed was created for television rather than the original theatrical release.
A September 5, 1951 Hollywood Reporter news item adds Harry Macking, Maynard Holmes and Mike Donovan to the cast, but their appearance in the film has not been confirmed.
