Zuni Mountains were the locations of digging according to the legend, but the film was shot mainly at Glen Canyon of Utah and Canyon de Chelly of Arizona, specifically Spider Rock. Parts of the film were also shot at Kanab Canyon, Paria, Sink Valley, and the Panguitch Fish Hatchery in Utah as well as Medford, Oregon. In the climax scenes, as the sun rises, the shadow of "Shaking Rock" grows longer. In reality, shadows become shorter as the sun rises higher.
