About this map

The gold-mining legacy of the Sierra Nevada foothills is etched into this landscape along the boundary of Nevada Co and Placer Co. Extensive hydraulic and placer mining operations define the terrain, most notably at the You Bet Diggings and Chalk Bluff Diggings near the community of You Bet. The complex water infrastructure required for these works is visible in the network of canals and reservoirs, including the Lava Cap Reservoir and the Lava Cap Mine located on Little Clipper Creek.

Legacy transportation routes cross the region, from the Southern Pacific railroad tracks winding through the southern ravines to the historic Donner Trail Markers and the Poorman Route. Settlements like Chicago Park, Peardale, and Magra serve as local hubs, while smaller landmarks like the Bear River Sch and the Loma Rica Airport provide specific points of interest for genealogists and local historians.
