1902 Map of Jackson

About this map

Jackson and the surrounding Sierra Nevada foothills appear here during a transformative era of mining and rail expansion. The landscape is defined by the deep canyons of the Mokelumne River and its forks, where gold-country outposts like Mokelumne Hill and Rich Gulch Mine were established. Industrial infrastructure is prominent, with the Amador Branch Railroad reaching Ione and the San Joaquin and Sierra Nevada Railroad serving Valley Springs. The map reveals a high density of small mining camps and waystations such as Jesus Maria, Jenny Lind, and Altaville, many of which were vital nodes in the 19th-century resource economy. To the south, the terrain rises toward the Bear Mountains and Gopher Ridge, while the legendary mining center of Angels Camp anchors the southeastern corner of the quadrangle, illustrating the complex network of flumes, mills, and camps that once dominated this region.
