About this map

The Capay Valley defines the northeastern portion of this study, where the settlements of Brooks and Cadenasso sit along the winding course of Cache Creek. This area transitions from the agricultural valley floor into the steep ridges of the Blue Ridge and the Vaca Mountains. The landscape is deeply incised by complex drainage systems including Tully Canyon, Carey Canyon, and Fiske Canyon, which feed into the Lake Berryessa basin at the southwestern corner.

Evidence of the region's geological and ranching history is found in landmarks like Berryessa Peak, Chimney Rock, and Scribner Mtn. Numerous water sources are documented throughout these canyons, including Medical Spring, Alder Spring, and Bear Spring, suggesting the importance of water access in this high-relief terrain. The map also records specialized land use such as the G3 Ranch Airport and the Alfalfa Patch Reservoir, alongside the Napa and Yolo county line tracing the crest of the interior ridges.
