1950 Map of Tunnel Hill

USGS Topo · Published 1952

About this map

Mining operations and timber management dominate this 1950s survey of the Eldorado National Forest, where the deep drainage of the Rubicon River forms a natural boundary between Placer and El Dorado counties. The landscape is marked by historical extraction, featuring the Boedner Mine near Pennsylvania Point and the Kenna Mine tucked within Missouri Canyon. Settlement is sparse, represented by isolated outposts like Barton Cabin and the small community at Quintette.
