1958 Map of Chiles Valley

USGS Topo · Published 1968

About this map

Chiles Valley and the surrounding Napa highlands are captured here during a period of significant hydrological change. The eastern edge of the map is dominated by the newly formed Lake Berryessa, with the Las Putas Boundary and the settlement of Rancho Monticello marking the interface between the rising waters and the historic land grants. This survey includes underwater contours provided by the Bureau of Reclamation, documenting the inundated landscape of the Putah Creek drainage.
