North Columbia, California
North Columbia was a California Gold Rush town on the San Juan Ridge in Nevada County, California. Originally known as Columbia, Columbia Hill, or The Hill because of its proximity to Columbia Hill, it started as a gold miners' camp around 1851. When a Post Office was established on May 29, 1860, the word "North" was added in order to differentiate the settlement from Columbia, California, another gold rush town in Tuolumne County, California. In 1878, when miners discovered that the Pliocene gravel bed upon which the town was built contained rich gold deposits, North Columbia was moved to its present location. But with the eventual curtailment of hydraulic mining, miners moved away. The post office closed in 1931. Eventually, North Columbia became an unincorporated part of Nevada City, California. Historic landmarks The Columbia Hill Schoolhouse still stands, though it has been converted into a cultural center, hosting events such as the North Columbia Folk Festival and the S ...

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners and inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
