1950 Map of Tunnel Hill

About this map

Bald Mountain and the Rubicon River anchor this mid-century survey of the California gold country, a landscape defined by deep drainages and legacy mining operations. The rugged divide between Missouri Canyon and Long Canyon is dotted with several named claims, including the Bedrock Mine, Kenna Mine, and Bootjack Mine. Small settlements and seasonal habitations appear as isolated outposts like Edison Cabin and Conner Cabin, while the Georgetown Divide provides the primary transit route along the ridges. The eastern portion of the map transitions into the Eldorado National Forest, where the Blodgett Experimental Forest was established for silvicultural study. Notable landmarks like the Bald Mtn Lookout and a remote Landing Field near Bacchi Ranch underscore the area's mix of resource management and early 20th-century aviation infrastructure.
