 The second unit filmed part of the prologue's 1912 segment from August 29 to September 3. The main unit began two days later with the circus train sequence at Alamosa, Colorado, on the Cumbres and Toltec Scenic Railroad. They filmed at Pagosa Springs on September 7, and then at Cortez on September 10. From September 14 to 16, filming of Indiana falling into the train carriages took place in Los Angeles. The production then moved to Utah's Arches National Park to shoot more of the opening. A house in Antonito, Colorado was used for the Jones family home. The production had intended to film at Mesa Verde National Park, but Native American representatives had religious objections to its use. When Spielberg and editor Michael Kahn viewed a rough cut of the film in late 1988, they felt it suffered from a lack of action. The motorcycle chase was shot during post-production at Mount Tamalpais and Fairfax near Skywalker Ranch. The closing shot of Indiana, Henry, Sallah and Brody riding into the sunset was filmed in Texas in early 1989.
