1958 Map of Chiles Valley

About this map

The Chiles Grist Mill stands as a focal point of early industrial heritage in the heart of the Catacuula Valley. This 1958 survey, updated with 1978 data, captures the rugged interior of Napa County before intensive modern development, dominated by the uplift of Greeg Mountain and the steep terrain of the Cedar Roughs. To the east, the rising waters of Lake Berryessa have transformed the landscape near Rancho Monticello, while the Pope Canyon Recreation Area marks the northern boundary of this upland territory. The map illustrates a network of springs and canyons, including Samuel Springs and Soda Spr, which once served as vital water sources for local ranching and early tourism. This document provides a clear view of the transition between the valley floors of Pope Valley and the formidable ridges that separate these inland basins from the Putah Creek drainage.
