Blue Ridge and Putas Ridge dominate the central topography of this survey, dividing the drainages of the Capay Valley from the rising waters of Lake Berryessa to the west. This period captures the landscape shortly after the completion of the Monticello Dam, showing the lake's spillway elevation and recreation areas at a time when the surrounding terrain remained largely defined by ranching and fire management. High points like Berryessa Peak Lookout Relay Sta and Anderson Mtn overlook a complex network of canyons, including Carey Canyon and Hog Canyon, which cut through the steep ridges. Traces of older transport and settlement are visible in the Toll Road and small outposts like Cadenasso and Brooks. Numerous springs, such as Medicel Spr and Sulphur Spr, indicate the important water sources for early landholders like those at Clark Ranch.
