Along the Rainbow Trail 1946

Directed by Edmund Reek

This 1946 entry in the "Movietone Adventures" series of shorts was in Technicolor when originally released. Narrated by Lowell Thomas, it is a trip from Medicine Hat in southern Utah down the rapids of the San Juan River ending with a view of the Rainbow Bridge, hence the title and the use of Tehnicolor. It was nominated for an Oscar for Best Short Subject, One-Reel.
