The town of Marfa near the Texas-Mexico border was used to simulate Bakersfield, California. A reason to support the use of the town is that there are many abandoned shafts dug out at the early 20-century. One of the shafts used in the film is a deep shaft, 60-70 feet that connects to a mechanically-dug perpendicular tunnel at the bottom. Other sets like the church where built from there.
