Dusty's Trail

Dusty's Trail was a 1973-1974 syndicated television series set in the 1800s about a small group of travelers separated from their wagon train who become lost. Dusty's Trail stars Bob Denver as Dusty, the assistant to the leader of a wagon train, and Forrest Tucker as Mr. Callahan, his irascible boss. Twenty-six episodes of the series were produced.

The series portrays passengers of a wagon and a stagecoach that have become separated from the main wagontrain on its way to California in the 1800s. The people in this group are the drivers of the wagon (Mr. Callahan) and the stagecoach (Dusty), a wealthy Eastern banker and his wife (Mr. and Mrs. Brookhaven), a dance-hall woman (Lulu), an educated man (Andy), and a farmer's daughter (Betsy). The show follows the adventures of this group attempting to find the main wagontrain.

The program was created for Denver by Sherwood Schwartz, who had previously created its progenitor, Gilligan's Island.
