 DATE: The initial scenes of the movie are shot in Arches National  Park (which is, as is stated, in Utah), and the troop dismounts at  Double Arch. Indy takes the Cross of Coronado from a cave near that  arch. However, there was no train line for miles in any direction at  the time of the story. The railroad line present in the area today  was built during the 1950s to serve a uranium processing mill at  Moab. The nearest railroad at the time of the story is 40 miles to  the north.
