USGS Topo · Published 1951About this map
Gold-bearing ridges and the deep canyons of the Middle Yuba River dominate this 1951 study of the northern Mother Lode country. The landscape is a map of industrial history, prominently featuring the Matakoff Diggings and numerous historical mining sites such as the Alaska Mine (Site), True Grit Mine (Site), and the Kate Hardy Mine. These operations follow the distinct geological formations of Chalk Ridge and the San Juan Ridge, where hydraulic mining and hard-rock tunneling once defined the local economy.
