Mooreville Ridge and Harrison Ridge dominate this rugged section of the Northern Sierra, where the boundaries of Plumas, Butte, Yuba, and Sierra counties converge. The landscape is defined by the legacy of hydraulic and hard-rock mining, with sites like Eureka Diggings, the Palace Mine, and the North Star scattered across the drainages of the North Fork Yuba River and Slate Creek. Small settlements and historic campsites such as Strawberry Valley, Brandy City, and Lewis Flat Camps are situated along steep ravines and ridges once bustling with gold-era activity.
