1958 Map of Chiles Valley

USGS Topo · Published 1961

About this map

Chiles Valley and the surrounding Napa County highlands are defined by a complex drainage system flowing toward the recently formed Lake Berryessa. This late-1950s survey documents the landscape shortly after the Monticello Dam project altered the regional geography, noting the spillway elevation of the new reservoir. Evidence of the area's agricultural and resort history is scattered across the terrain, from the landmark Chiles Grist Mill along Chiles Creek to the secluded Samuel Springs and Rancho Monticello. The map tracks several rugged corridors such as Cedar Roughs and Trout Creek Ridge, while also detailing the western reach of Lake Hennessey. Geodetic markers like McCurdy VABM provide high-elevation reference points overlooking the intricate canyons of Husman and Wood.
