The boundary between El Dorado Co Sacramento Co cuts through a landscape defined by gold-rush era water infrastructure and early 1950s hydraulic engineering. The Folsom Reservoir and its spillway dominate the northwest, while the older Natomas Ditch winds along the slopes, a relic of the complex flumes and ditches required for mining. Significant industrial history is evident in the Dredge Tailings near Willow Cr, marking the scale of earth-moving operations in the region.
