Available in PDF, EPUB and Kindle. Book excerpt: The Northern Gold Fleet is the story of how new gold-dredging technology was applied to the rich placers of the Far North from 1899 to the present, leading to mass production and economies of scale that made previously unprofitable resources profitable. The bucket-ladder dredge was a single, complex apparatus that rivaled ocean freighters in size. At once ugly, spectacular, and awesome, the dredges dug, classified materials, and performed gold-saving and tailing-disposal functions. A richly illustrated and comprehensive history. The Northern Gold Fleet is part environmental, part technological, part corporate, part labor, and part Alaskan in its thrust, offering a picture - both dazzling and absorbing - of how new technology simultaneously helped build the economy and lay waste the resources of Alaska.

Available in PDF, EPUB and Kindle. Book excerpt: A History of Gold Dredging in Idaho tells the story of a revolution in placer mining—and its subsequent impact on the state of Idaho—from its inception in the early 1880s until its demise in the early 1960s. Idaho was the nation’s fourth-leading producer of dredged gold after 1910 and therefore provides an excellent lens through which to observe the practice and history of gold dredging. Author Clark Spence focuses on the two most important types of dredges in the state—the bucket-line dredge and the dragline dredge—and describes their financing, operation, problems, and effect on the state and environment. These dredges made it possible to work ground previously deemed untouchable because bedrock where gold collected could now be reached. But they were also highly destructive to the environment. As these huge machines floated along, they dumped debris that harmed the streams and destroyed wildlife habitat, eventually prompting state regulations and federal restoration of some of the state’s crippled waterways. Providing a record of Idaho’s dredging history for the first time, this book is a significant contribution to the knowledge and understanding of Western mining, its technology, and its overall development as a major industry of the twentieth century.

Book excerpt: Gold Dredge No. 8 is one of the most significant relics of mining history in Alaska. Currently located at her final resting place, just north of Fairbanks, dredge No. 8 was dubbed the "Queen of the Fleet" during her years of operation in the Goldstream Valley. Gold Dredge No. 8 is the only landmark of its kind that is open to the public. Every summer, she provides a wonderful experience to thousands of visitors who come to Fairbanks looking for adventure and the chance to experience firsthand the history for which Fairbanks's mining pioneers are renowned. Author Maria Reeves explores the history of Gold Dredge No. 8 as well as visionary men, lie Norman C. Stines and James M. Davidson, who made dredging in the Fairbanks district not only a reality, but also provided enough economic stability to bring the struggling town of Fairbanks back to life. Gold Dredge No. 8 was a placer mine that drew water from another local engineering landmark, the Davidson Ditch. In this book, you'll learn about the crew that operated Gold Dredge No. 8 as well as the hardships these dredge men faced on a daily basis. You'll be able to take a photographic tour of Gold Dredge No. 8 as she is now, and learn about efforts to preserve Pleistocene fossil remains that were unearthed during the stripping process. You'll learn why the gold standard initially helped mining and find out why Gold Dredge No. 8 was shut down in 1959.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Gold Dredging in the United States The recovery of gold from sands and gravels is one of the oldest forms of mining; it antedates history and has been practiced by savage peoples. In North America the search for placer gold has been a powerful agency in the exploration and development of unknown regions and has profoundly influenced the course of our civilization. With the progress of invention, the improvements in machinery, and the availability of large capital for the conduct of great operations, the tendency in placer, as in many other branches of mining, has been toward the working of extensive but comparatively low-grade deposits. The early miner washed the rich spots in stream beds or terraces with his pan, his long tom, and his primitive sluice. Then followed the growth of hydraulic mining and the use of giants supplied with water under pressures of hundreds of pounds to the square inch that could work at a profit gravels whose gold tenor was less than 3 cents to the cubic yard. Finally came the dredge that could handle deposits lying so far below water level as to be beyond attack by other methods. Although the gold dredge was first successful on a commercial scale in New Zealand, it has reached its present strength and efficiency in this country and its development is a monument to the daring, per severance and technical skill of the many men, mine owners and engineers who have each contributed something to the final result. The Bureau of Mines, authorized to conduct investigations for the purpose of increasing efficiency in the mineral industries, had its attention called some years ago to the need of a comprehensive report on gold dredging in the United States. The director of the bureau recognized that such a report should summarize the development of the gold dredge, should describe in detail the essential features of present-day dredges, should discuss the facts that determine whether a placer deposit can be profitably dredged, and should point out the approved methods of prospecting placer ground and of operating dredges.
