Locations of lode gold prospects and mines shown on the map were obtained from the U.S. Relief on the oblique map has a 3:1 vertical exaggeration and appears as if viewed from a 30° angle above the horizon. Form lines sketched over this framework graphically portray the physiographic configuration of the region. Geological Survey 1:500,000-scale topographic map of Nevada, using an isometrograph, a mechanical instrument that produces an oblique framework by tracing individual contours. Geological Survey 1:500,000-scale topographic map of California and the 1976 U.S. This oblique map illustrates the relation of the different gold-bearing environments to each other and to the general terrain of the northern Sierra Nevada. In addition to production from the complex vein systems of the historically famous Mother Lode and associated East Gold Belt and West Gold Belt, large amounts of gold have also been recovered from the Grass Valley-Nevada City and other isolated lode districts and from Tertiary river channels and Quaternary alluvium. Gold has been found in a variety of geologic environments in the region. Dramatic increases in gold prices in the past decade coupled with recent advances in extractive techniques have revitalized prospecting, and major deposits are currently being explored and developed. Mining was continuously active, somewhere in the area, from the discovery of gold until World War II when mining was legally prohibited. Gold was first discovered, in this region, on the American River at Coloma in 1848, triggering the famed California gold rush. The bulk of this gold was recovered from the western slope of the northern half of the Sierra Nevada between the Merced River in the south and the Feather River to the north, a distance of about 170 mi. Two of the markers are missing.More than a third of the gold produced by the United States was mined in California.
