About this map

Gold-bearing ridges and early emigrant routes define this landscape along the border of Nevada and Placer counties. The map traces the historic path of the Donner Trail Markers, which winds through the central terrain near Chicago Park. This agricultural and residential hub is surrounded by a legacy of hydraulic and hard-rock mining, evidenced by the numerous Placer Diggings and industrial sites like the Lava Cap Mine and the Banner Mine (Inactive).

Transportation infrastructure reflects the region's development from the mid-19th century into the post-war era, from the winding Southern Pacific railroad line passing through Magra to the Loma Rica Airport near Peardale. To the east, the ghost of earlier settlements is marked at Secret Town (Site), located near the steep descent of Secret Ravine. The rugged topography is further illustrated by landmarks such as Cape Horn and Hayford Hill, which overlook the deep canyons of the Bear River.
