2012 Map of Graniteville

About this map

Graniteville anchors this survey of the Sierra Nevada highlands, where the industrial legacy of California’s hydraulic and hard-rock mining era is etched into the landscape. The map details a complex water management system essential for high-elevation operations, featuring the Bowman Tunnel and Clear Creek Tunnel alongside massive catchments like Bowman Lake and the Weaver Reservoir. Evidence of early processing sites and mountain camps is preserved through labels like the Old Condon Mill and the settlement of Gaston, which sits along the Gaston Rd near Gaston Ridge. High mountain meadows and flats, such as Loney Meadow and Murphy Flat, break the steep drainage patterns of the Middle Yuba River and its numerous tributaries. This 2012 update documents the transition of these historic industrial sites into recreation hubs, noting multiple campgrounds like McMurray Campground and Carr-Feeley Campground that now occupy the rugged terrain once defined by mills and mining claims.
