About this map

Eldorado National Forest encompasses this mid-century landscape where industry and infrastructure meet the Sierra Nevada foothills. The mapping of this era highlights a transition from early timber and mineral extraction toward forest management, evidenced by the numerous fire prevention and monitoring sites such as the Leon Fire Tank, Harrel Fire Tank, and the Iron Mtn Lookout. The lumber industry's footprint is clear, with several historical milling locations documented, including the Girard Mill (Site) and Tuman Mill (Site), alongside active logging routes and the Caldor Ranger Sta.

Deeply integrated into the geography of Baltic Ridge and Scott Ridge, the map identifies family-named settlements and stations like Cooks Station, Hams Station, and Bryants. Mining history is represented by the Spread Eagle Mine and Robert Lee Mine, while the winding courses of the North Fork Cosumnes River and its many tributaries, such as Sly Park Creek, define the water economy of El Dorado and Amador counties.
