Gold Canyon
Gold Canyon is located a few miles south of Alleghany, California, on the border between Sierra and Nevada Counties. The middle fork of the Yuba River flows through the canyon. Gold mining began in Gold Canyon in the early 1850s and has continued to present day. Three major gold mines are located here: German Bar Mine, Gold Canõn Mine, and Independent Mine. In 1859 the Gold Canyon area became the first to ban Chinese miners, after a group of 50 Chinese miners had earned a reported $35,000. This decision was adapted elsewhere, and laid the foundation for Senator William Morris Stewart William Morris Stewart (August 9, 1827April 23, 1909) was an American lawyer and politician. In 1964, he was inducted into the Hall of Great Westerners of the National Cowboy & Western Heritage Museum. Personal Stewart was born in Wayne County ...'s U.S. Mining Act of 1866, which prohibited Chinese workers from holding original mining claims. Before power was brought to the area, the nearby Plu ...

Sierra County, California
Sierra County () is a county located in the U.S. state of California. As of the 2020 census, the population was 3,236, making it California's second-least populous county. The county seat is Downieville; the sole incorporated city is Loyalton. The county is in the Sierra Nevada, northeast of Sacramento on the border with Nevada. History Sierra County was formed from parts of Yuba County in 1852. The county derives its name from the Sierra Nevada. Prior to the California Gold Rush, the area was home to both the Maidu and the Washoe peoples. They generally summered in the higher elevations to hunt and fish, and returned to lower elevations for the winter months. After the discovery of gold in the Sierra foothills sparked the California Gold Rush, more than 16,000 miners settled in Sierra County between 1848 and 1860. Most mining settlements in the county sprung up along the North and Middle Forks of the Yuba River, both of which had rich deposits of gold. While some of the min ...

Nevada County, California
Nevada County () is a county located in the U.S. state of California, in the Sierra Nevada. As of the 2020 census, the population was 102,241. The county seat is Nevada City. Nevada County comprises the Truckee-Grass Valley, CA Micropolitan Statistical Area, which is also included in the Sacramento- Roseville, CA Combined Statistical Area, part of the Mother Lode Country. History Created in 1851, from portions of Yuba County, Nevada County was named after the mining town of Nevada City, a name derived from the Sierra Nevada Mountains. The word ''nevada'' is Spanish for "snowy" or "snow-covered." Charles Marsh was one of the first settlers in what became Nevada City and perhaps the one who named the town. He went on to build extensive water flumes/ditches/canals in the area, and was influential in the building of the first transcontinental railroad as well as the Nevada County Narrow Gauge Railroad. Nevada City was the first to use the word "Nevada" in its name. In 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yuba River
The Yuba River is a tributary of the Feather River in the Sierra Nevada and eastern Sacramento Valley, in the U.S. state of California. The main stem of the river is about long, and its headwaters are split into three major forks. The Yuba River proper is formed at the North Yuba and Middle Yuba rivers' confluence, with the South Yuba joining a short distance downstream. Measured to the head of the North Yuba River, the Yuba River is just over long. The river drains , mostly in the western slope and foothills of the Sierra Nevada. The average runoff of the Yuba River basin is approximately per year, providing about one-third of the flow of the Feather River, and 10 percent of the flow of the Sacramento River, which the Feather ultimately drains into. Since the early 20th century, irrigation and hydropower diversion projects have gradually reduced the river's flow. The river's name comes from the local tribe, the Nisenan, word for "waterway," 'uba seo. It is spelled in ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold Mining
Gold mining is the extraction of gold resources by mining. Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning. However, with the expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation. In the 20th and 21st centuries, most volume of mining was done by large corporations, however the value of gold has led to millions of small, artisanal miners in many parts of the Global South. Like all mining, human rights and environmental issues are common issues in the gold mining industry. In smaller mines with less regulation, health and safety risks are much higher. History The exact date that humans first began to mine gold is unknown, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria. The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 700 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Placer Mining
Placer mining () is the mining of stream bed (Alluvium, alluvial) deposits for minerals. This may be done by open-pit mining, open-pit (also called open-cast mining) or by various surface excavating equipment or tunneling equipment. Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are often found in Alluvium, alluvial deposits—deposits of sand and gravel in modern or ancient stream beds, or occasionally glacial deposits. The metal or gemstones, having been moved by stream flow from an original source such as a vein, are typically only a minuscule portion of the total deposit. Since gems and heavy metals like gold are considerably denser than sand, they tend to accumulate at the base of placer deposits. Placer deposits can be as young as a few years old, such as the Canadian Queen Charlotte beach gold placer deposits, or billions of years old like the Elliot Lake uranium paleoplacer within the Huronian Supergroup i ...

Canyons And Gorges Of California
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examples of mountain-type c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of Nevada County, California
