1959 Map of Rumsey

About this map

Rumsey lies at the southern edge of this landscape, situated along the banks of Cache Creek where the waterway enters the broad valley of Cañada de Capay. The terrain is defined by a dense network of drainages and ridges, including the appropriately named Petroleum Creek and several Oil Test Wells, indicating early mineral exploration in the region. To the south, the Blue Cliffs overlook the valley floor, while the rugged backcountry is marked by features such as Whisky Creek and Elk Creek. This 1959 survey records the border between Colusa and Yolo counties as it traverses the upland ridges. Small settlements like Graves and the Rancheria provide key points of reference for local historians, alongside technical infrastructure like the Gaging Sta near the creek bend.
