The La Plata River corridor serves as the central artery for this San Juan County landscape, supporting a complex network of irrigation infrastructure including the Enterprise Ditch, Highland Park Ditch, and Cunningham Ditch. This 1963 survey, updated with 1978 aerial data, documents the agricultural and industrial character of the valley floor contrasted against the high terrain of the Southern Ute Indian Reservation. The small settlement of La Plata is the focal point for local history, featuring the La Plata Cem and nearby Gravel Pits.
