In the canoe scene when Drew and Wabi leave the cabin with the rescued Mountie, when the Mountie is shot by one of the villains, he falls backwards toward Wabi. In the very next scene he's lying in the other direction toward Drew.
The suits the passengers are wearing in the train, the decorum inside the coaches, as well as the train itself, are all indicative of the era in which this film was created. A telegram is also mentioned. However, the dress of the RCMP officers, the use of the Union Jack instead of the Canadian Red Ensign, the dress of the Native Americans, and the general lack of modern technology in the outposts in this film indicate more a 19th century setting. Thus, the audience is left very unclear as to what era the story is supposed to be set in.
When the Mounties and the deputies are chasing the villains one of the villains is shot from his horse. You can see a rope tied to him after he falls.
The filming location (California) and the plot's setting (somewhere in the vicinity of the U.S.-Canada border) creates ambiguity as to where on the continent the story takes place. The scenery leads one to think that it takes place in the Rocky Mountains. However, a "Fort Nipigon" is mentioned. Nipigon, Ontario, is in the region of Lake Superior, nearly 200 kilometres from Minnesota.
