The Guide tells the story of 14 stops and more than 20 sites along the Route of the Silver Kings in the Leadville Mining District, one of the richest and best-known mining camps in the United States.  Mining began when placer gold was discovered in April 1860.  140 years mining ended January 1999 when American Smelting and Refining Company’s Black Cloud mine and mill closed.  The U.S. Bureau of Mines estimated that there are 1329 shafts, 1628 prospect holes and more than 200 miles of workings in the district, U.S. Bureau of Mines, R.I. 4581, p. 13.  Seventeen smelters are listed in the May 30, 1879 issue of the Leadville Daily Evening Chronicle.  The district was served by 3 railroads; the Rio Grande and the Denver South Park and Pacific (joint track use) arrived in 1880. Denver South Park and Pacific, (Colorado and Southern) exclusive route via Boreas and Fremont Passes 1884. The Colorado Midland arrived in 1887.

On your tour, please treat the mining district with care; it is located entirely on private land. The few remaining structures are fragile and dangerous.  Respect “No Trespassing” signs; do not enter mine shafts or tunnels; no rock hounding, treasure hunting, metal detecting or digging.
