1961 Map of Porterville

About this map

Porterville sits at the northern edge of this high-elevation terrain, where the East Canyon Creek valley opens into the surrounding mountains of Morgan County. The settlement pattern is defined by the water, with the Richville Diversion Dam regulating local flows and the Porterville Cem marking the historic community center. Topography dominates the landscape, characterized by numerous steep drainages such as Hardscrabble Creek, Cottonwood Canyon, and Adams Hollow that feed into the larger creek systems. Historical land use is visible through several pack routes, including the Arthurs Fork Trail and Pine Canyon Trail, which likely served as early mountain access points before modern development. Notable landmarks like Whites Crossing and The Narrows indicate specific points of geographic constraint that shaped the local travel and irrigation infrastructure of the mid-20th century.
