2021 Map of Rumsey

About this map

Rumsey lies at the northern reach of the Capay Valley, where the landscape transitions into the steep ridges and drainage basins of the inner Coast Ranges. This modern survey illustrates the geographical transition between the agricultural lands of the Sacramento Valley and the complex terrain to the west. The prominent Blue Cliffs rise sharply above Cache Creek, which serves as the primary hydrological artery for the region. A network of seasonal drainages, including Whisky Cr, Petroleum Creek, and Salt Creek, carves through the uplands, defining the local topography. The boundary between Colusa Co and Yolo Co cuts across the northern half of the sheet, while local routes like Co Rd 41A and Rd 41 provide access to the foothills and canyons such as Benjamin Canyon.
