摘要

This paper presents the history of gold mining by dredge, with particular reference to the Snowstorm dredge, located near Fairplay, Colorado. This machine is the last Colorado representative of an industry, an era and a form of technology. Mining dredges were huge and noisy, yet they were welcomed as a form of economic relief to the old industry of placer mining. Streambed mineral deposits, especially gold, have attracted mankind for thousands of years. In the American West, placer gold was mined first by panning, later by sluice and hydraulic methods, but none was very economical. After some early and unsuccessful American attempts, mining dredge technology got its start in New Zealand. From an ox-hide stretched over an iron ring, all the way to steam and electric-powered boats with bucket ladders, New Zealand's engineers led the way in the last part of the Nineteenth Century. Successful American dredging began in Montana in 1896, and soon spread to other states. San Francisco became the home of dredge manufacturers. English-born engineer Ben Stanley Revett brought gold dredging to Colorado. After a few unsuccessful attempts, in 1905 he designed his own dredge, called the "Reliance," which incorporated stronger timber and larger bucket lines for deeper digging. The dredge was an immediate success, for Revett and the area. Colorado dredging continued as a successful industry through the 1920s, but suffered financial reverses in the Depression. Finally, World War II orders shut down the industry as non-essential. It did not return in most places. However, the Snowstorm dredge, built just before the war, operated up to 1976. This machine contains many features of the original American dredges. Today the Snowstorm dredge stands as. a lone reminder of this important part of mining history, and should be the subject of historic preservation.
