Malakoff Diggins State Historic Park
Malakoff Diggins State Historic Park is a state park unit preserving the largest hydraulic mining site in California, United States. The mine was one of several hydraulic mining sites at the center of the 1882 landmark case '' Woodruff v. North Bloomfield Mining and Gravel Company.'' The mine pit and several Gold Rush-era buildings are listed on the National Register of Historic Places as the Malakoff Diggins-North Bloomfield Historic District. The "canyon" is long, as much as wide, and nearly deep in places. Visitors can see huge cliffs carved by mighty streams of water, results of the mining technique of washing away entire mountains of gravel to wash out the gold. The park is a drive north-east of Nevada City, California, in the Gold Rush country. The park was established in 1965. History The Malakoff mine pit on the San Juan Ridge is the impetus for one of the nation's first environmental protection measures. In 1850 there was little gold left in streams. Miner ...

Hydraulic Mining
Hydraulic mining is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment.Paul W. Thrush, ''A Dictionary of Mining, Mineral, and Related Terms'', US Bureau of Mines, 1968, p.560. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal. Hydraulic mining developed from ancient Roman techniques that used water to excavate soft underground deposits. Its modern form, using pressurized water jets produced by a nozzle called a "monitor", came about in the 1850s during the California Gold Rush in the United States. Though successful in extracting gold-rich minerals, the widespread use of the process resulted in extensive environmental damage, such as increased flooding and erosion, and sediment blocking waterways and covering farm fields. These problems led to its legal regulation. Hydraulic mining has been used in various forms aroun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Corral
French Corral is an unincorporated community approximately five miles west of California State Highway 49 in Nevada County, California. It was one of the first of several historic California gold rush mining camps along the San Juan Ridge. The name was literal as the town grew around a mule corral built by the first settler in the area, a Frenchman, in 1849. It had a post office during the period of 1859 through 1945. Few original structures remain besides an old Wells Fargo Bank building. Location Based on roads and trails used during its time, French Corral was located between the small towns of Rough & Ready and North San Juan. On a present-day map, French Corral is located in the extreme northwest corner of Nevada County, California. Originally, French Corral was part of nearby Bridgeport Township, the third locality in the county in terms of population and wealth during the mining years. French Corral is part of a thermal belt that runs from the town site to the Be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protected Areas Of The Sierra Nevada (United States)
The protected areas of the Sierra Nevada, a major mountain range located in the U.S. states of California and Nevada, are numerous and highly diverse. Like the mountain range itself, these areas span hundreds of miles along the length of the range, and over 14,000 feet of elevation from the lowest foothills to the summit of Mount Whitney. The Sierra Nevada, as a natural region, does not have exactly defined borders. In particular, to the north, there is a wide transition zone where the Cascade Range and the Sierra Nevada meet. As a result, it is difficult to delineate a border between these two mountain ranges. This list uses the common definition of the Sierra Nevada as the mountain range extending from Fredonyer Pass in the north to Tehachapi Pass in the south. It is also difficult to delineate between the Sierra Nevada mountains, the range's foothills, and the Central Valley; this article also considers any elevated and hilly terrain east of the flat Central Valley to be par ...

History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Mining Museums In California
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and ...
