2018 Map of Rumsey

About this map

Rumsey sits at the southwestern edge of this landscape, marking a transition between the elevated terrain of Benjamin Canyon and the agricultural floor of the Capay Valley. The map details a complex network of seasonal drainages, including Petroleum Creek and Salt Creek, which flow eastward toward the Sacramento Valley. This topography is defined by the sharp rise of the Blue Cliffs over Cache Creek, illustrating the physical barriers that shaped early transit and settlement patterns along the county line between Colusa and Yolo. The presence of Petroleum Creek Rd and Boles Rd suggests the continued importance of these drainage corridors for accessing the more interior sections of the foothills. Researchers can trace the water-dependent geography from Little Buckeye Cr in the south to the northern reaches of Rich Cr.
