The San Pedro River corridor defines the western edge of this 1970s survey, where irrigation and transport infrastructure converge near the settlement of Saint David. This area of the San Pedro Valley is characterized by the Saint David Ditch and its proximity to the Southern Pacific railroad line, which skirts the valley floor. Moving eastward, the terrain transitions into the wide, arid expanse of Lonesome Valley, marked by ephemeral watercourses like Dragoon Wash and Sheep Wash. Several small stops and sidings along the rail and road network, including Sibyl, Fenner, and Adamson, illustrate the rural settlement patterns before later regional development. Local civic life is anchored by the High Sch in Saint David, while industrial activity is noted by a Substation and several Borrow Pit locations near the Sibyl Interchange.
