About this map

The confluence of the North Fork American River and the Middle Fork American River defines this rugged section of the Sierra Nevada foothills, where mining legacy and agricultural pockets intersect. Significant gold-mining sites such as the Grit Mine, Bowman Mine, and the Shenanigan Mine are scattered across the landscape, particularly near the settlement of Spanish Dry Diggings. The terrain is characterized by steep canyons like Maine Bar Canyon and prominent ridges such as the Georgetown Divide.

Along the rivers, numerous bars including Buckeye Bar, Mammoth Bar, and Maine Bar testify to the intensive placer mining history of the region. The map also records early twentieth-century infrastructure, featuring Lake Clementine, the Greenwood Bridge, and the small community of Greenwood. Isolated holdings like Penobscot Farm and Butcher Ranch highlight the sparse but persistent settlement patterns within the deeply incised river valleys of El Dorado and Placer counties.
