(The caption on the verso of the photograph may be incorrect because this dredge may have been located in the Fairplay area, Park County.) In operation, a bucket line excavated placer gravel and fed it into the dredge where it was milled, and then its stacker deposited the tailings along the river channel. Gold placers were discovered in the Breckenridge area in 1859. Although most of the rich and easy placers were exhausted within a few years, placer mining continued using new technologies into the 1900s. The first dredge began operations in the area in 1906 and dredging continued into the 1930s.Rights management statement available at: http://library.mines.edu/digital/rights.htmlDredges and dredgingGold mines and miningMiningPlacer miningStillImage
