Clifton and the surrounding mining districts are at the center of this industrial and mountain landscape at the dawn of the twentieth century. The topography reveals the intense mineral extraction efforts of the era, centered on the Coronado Mine and the industrial infrastructure of the Shannon Smelter. The San Francisco River cuts through the canyon floor, providing a vital corridor for the Southern Pacific Railroad to reach these mountain outposts.
