In the 20th century, both tourists to the West, and avid readers enjoyed the visual imagery of the frontier. The Western movies provided the most famous examples, as in the numerous films of John Ford. He was especially enamored of Monument Valley. Critic Keith Phipps says, "its have defined what decades of moviegoers think of when they imagine the American West." The heroic stories coming out of the building of the transcontinental railroad in the mid-1860s enlivened many dime novels and illustrated many newspapers and magazines with the juxtaposition of the traditional environment with the iron horse of modernity.
