Silver mining in Colorado. Silver mining in Colorado has taken place since the 1860s. In the past, Colorado called itself the Silver state. (Nevada also calls itself the Silver state. Idaho, however, actually produces the most silver in the US.)
In 186, prospectors discovered silver, lead, and zinc deposits in the canyons and mountains southeast of Salt Lake City, particularly in Big Cottonwood, Little Cottonwood, and Parley's Canyons. By 1870 towns like Alta and Park City had sprung up and taken on the aspect of other mining towns found throughout the West.
