1959 Map of Brooks

About this map

Blue Ridge and Rocky Ridge dominate this landscape along the boundary of Yolo and Napa Counties, where the terrain drops sharply toward the eastern shore of Lake Berryessa. The map captures a transition from the elevated peaks of Anderson Mtn and Berryessa Peak to the canyon-cut lowlands. In the northeast, the settlement of Brooks and the Rumsey Rancheria sit near the winding course of Cache Creek. This region, documented through aerial photography from 1957 and updated in the late 1980s, reveals a network of fire-access routes and a Toll Road threading through deep drainages like Brick Chimney Canyon and Fiske Canyon. The presence of numerous named water sources, such as Medical Spr and Sulphur Spr, points to the area's geological character and its history of mineral-rich springs.
