1958 Map of Chiles Valley

About this map

Lake Berryessa dominates the northeastern corner of this Napa County landscape, showing the reservoir and its underwater contours as surveyed during the late 1950s. The map documents the rural character of the region just as the newly created lake was altering the local geography, particularly around Rancho Monticello and Putah Creek Park. To the west, the topography transitions into the steep terrain of Cedar Roughs and Trout Creek Ridge, separating the Berryessa basin from the agricultural pockets of Pope Valley and Chiles Valley.
