John Hillers was an American photographer and cartographer active in the late nineteenth century, best known for his documentation of geological surveys and landscape exploration in the American West. Working primarily with large-format albumen and gelatin dry plate processes, he produced extensive visual records of canyon systems, river valleys, and indigenous settlements across the Colorado Plateau and surrounding regions. His photographs served both scientific and archival purposes, establishing a visual record of geological formations and settlements during a period of rapid Western expansion.
