About this map

Michigan Bluff and the surrounding gold-country ridges of Tahoe National Forest define this mid-century look at California's high Sierra. The landscape is a network of historic extraction sites, tracing the path of 19th-century hydraulic and hard-rock mining along the North Fork American River. Notable locations include the Last Chance Cem and the former settlement at Damascus, illustrating the era's transition from boomtowns to remote forest outposts.

A complex infrastructure of old ditches and tunnels is documented here, such as the Honey Tunnel and Eureka Tunnel, which supported extensive operations like the Hidden Treasure Mine. Genealogists and historians can locate specific sites like Forks House (Site) and Deadwood (Site), while the presence of the Greek Store Guard Sta and Brushy Spring Guard Station reflects the early management of the Placer County timberlands and redwoods.
