Nice Kanab locations
Pretty sure I spotted the following locations from other movies:
the lake where the prisoners bathe - same lake the Indians chase Henry Fonda across in 'Drums Along the Mohawk'; Aspen Mirror Lake
white bluffs that Joel McCrea & others watch wagon train from - opening of 'Western Union' - Paria Canyon
Jeff Corey's hideout - Virginia Mayo's ranch from 'Fort Dobbs' ; Kanab Canyon
sand dunes the four riders pass on their way to Sante Fe - Clint Eastwood meets the Comancheros in 'Outlaw Joey Wales ; Coral Pink Sand Dunes
