About this map

Sierra Valley and the surrounding timberlands of the Plumas National Forest and Tahoe National Forest meet at this mountain-valley junction. The settlement of Calpine serves as a central hub, situated near the Calpine Res and an early Landing Strip. The map reveals the legacy of the local timber and transport economy through the presence of an Old Railroad Grade winding through Folchi Meadows and near McPherrin Camp. This 1981 survey documents a transition from industrial exploitation to a landscape increasingly defined by public forest management. Water resources are plentiful, with Knuthson Creek and the West Fork Carman Valley feeding the lower meadows, while several Flowing Wells and a complex system of Canals and Channels support the agricultural flats of the valley floor.
