Harper and the broader Harper Valley dominate the southwestern corner of this high-desert landscape, where the Malheur River cuts through the basin. The map reveals an intricate network of irrigation infrastructure essential for local agriculture, including the Vale Oregon Main Canal and the Little Valley Lateral. This managed water system reflects the transformation of the arid terrain into a productive valley, a process further evidenced by the naming of Little Valley itself.
