About this map

Monticello Dam stands as the primary engineered landmark on this map, holding back the waters of Lake Berryessa at Devils Gate. The terrain here marks a sharp transition between the rugged elevations of the Vaca Mountains and Blue Ridge to the west and the expansive Sacramento Valley to the east. As Putah Creek flows out from the dam, it winds toward the settlement of Winters, which serves as a gateway between the mountainous coastal ranges and the agricultural heartland.

The landscape is deeply incised by numerous seasonal drainages and springs, including Chickahominy Slough and Union School Slough. High points like Edgar Peak and Wild Cow Mtn offer significant vertical relief above Thompson Canyon and Perkins Canyon. The network of county roads and named ridges, such as Pleasants Ridge and Crane Ridge, provides a detailed view of the area's rural infrastructure and natural boundaries at the intersection of Yolo, Napa, and Solano counties.
