1949 Map of Railroad Flat

USGS Topo · Published 1949

About this map

Railroad Flat and Glencoe anchor this survey of the Sierra Nevada foothills shortly after the Second World War. The landscape is defined by the deep incisions of the Middle Fork Mokelumne River and the North Fork Calaveras River, which carved the gold-bearing canyons that drove the region's 19th-century boom. Evidence of this persistent mineral interest remains visible through numerous claims, including the Etna Mine, Wolverine Mine, and the Jeff Davis Mine near Independence.
