About this map

Ruth Lake dominates this mountain landscape, held by the Robert W Matthews Dam along the Mad River. This late 1970s survey illustrates a region defined by federal forest management, where the Six Rivers National Forest and Trinity National Forest meet. The map reveals a complex network of waterways including Hettenshaw Creek and the Van Duzen River, which carve through prominent peaks like Grizzly Mountain and Hettenshaw Peak.

Remote settlements and family-named landmarks provide significant detail for local historians, specifically the Old Womans Home and the Old Willborn Ranch located south of Hettenshaw Valley. Infrastructure such as the Zenia Road and various 4WD trails offer a look at the backcountry accessibility of the era, while features like Mad River Rock and Hetten Rock serve as clear navigational anchors in the high-elevation terrain.
