Altamont Speedway sits near the northern boundary of this landscape, where the foothills of the Diablo Range transition into the San Joaquin Valley. This 2012 survey documents a complex network of water infrastructure, dominated by the Governor Edmund G Brown California Aqueduct and the Delta-Mendota Canal, which cut southeast across the terrain. Small settlements and former industrial sites like Tesla, Pottery, and Carnegie are situated along Corral Hollow Cr in the south, reflecting the region's legacy of mining and manufacturing. The central portion of the map is defined by the community of Midway and its associated Midway Siding, illustrating the intersection of rail transport and rural development. From Redmond Cut to the drainage of Patterson Run, the map details a topography shaped by both natural watercourses and massive engineering projects.
