USGS Topo · Published 1965About this map
Gold mining operations and remote Sierran settlements dominate this mid-century survey of the Tahoe National Forest region. The community of Alleghany serves as the focal point, surrounded by a high density of quartz and drift mines that reveal the area's industrial legacy. Notable active and inactive workings include the Sixteen To One Mine, Tightner Mine, and Yellow Jacket Mine, which trace the mineral-rich veins of Pliocene Ridge and Lafayette Ridge.
