1958 Map of Chiles Valley

About this map

Chiles Valley and Catacula Valley form the heart of this Napa County landscape, where the ridges of Cedar Roughs and Trout Creek Ridge define the steep topography. Grounded in mid-century land use, the map documents the transition of the regional water system, most notably the presence of Lake Berryessa at the northeastern corner. Historical industry and settlement are represented by the Chiles Grist Mill along the Pope Valley Road and the established resort sites at Samuel Springs and Rancho Monticello. These features reflect a period before modern development, when rural commerce revolved around small springs and local milling. The survey also details the complex drainage networks of Maxwell Creek and Putah Creek Park, providing a clear view of the canyon-and-valley structure that has long dictated movement through these coastal ranges.
