2015 Map of Rumsey

About this map

Rumsey sits at the northern end of the Capay Valley, where the waters of Cache Creek emerge from the steep coastal range into the broader flats of the Sacramento Valley. This 2015 survey details the intersection of Yolo and Colusa counties, a landscape defined by sharp elevation changes and deep drainage systems like Benjamin Canyon and Rumsey Canyon. The rugged topography north of the settlement is marked by the Blue Cliffs and an intricate network of seasonal watercourses, including Petroleum Creek, Whisky Cr, and Elk Creek. Historical land divisions are clearly visible through the Public Land Survey System grid, while local transit is anchored by routes such as Co Road 41A and Sand Creek Rd. The map illustrates the transition from the secluded, narrow canyons to the fertile agricultural basin that begins near the southern edge of the quadrangle.
