Fricot Nugget
The Fricot Nugget is a crystalline gold nugget found in El Dorado County, California in 1865 during the California Gold Rush by William Russell Davis. The nugget was found in Davis' Grit Mine at Spanish Dry Digging's at a depth of 60.96 metres (200 feet). The Fricot Nugget weighed 5.69 kilograms (201 ounces or 12.56 pounds), and was later shipped to New York where it was purchased by Jules Fricot for approximately $3,500. Fricot took the nugget to Paris for the 1878 Paris Exposition. Following the Paris Exposition, the Fricot Nugget was missing until 1943 when it was found in a safe deposit box in Calaveras County, California. The nugget came close to being stolen in 2012 when a theft occurred at the California State Mining and Mineral Museum where the nugget was being held, however safety measures protected the Fricot Nugget from the intruders. The nugget is listed as the eleventh largest gold nugget ever found and is the second largest gold nugget found in the United States of Ame ...

Crystalline
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. The word ''crystal'' derives from the Ancient Greek word (), meaning both " ice" and " rock crystal", from (), "icy cold, frost". Examples of large crystals include snowflakes, diamonds, and table salt. Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. Polycrystals include most metals, rocks, ceramics, and ice. A third ca ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium ( gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroau ...

El Dorado County, California
El Dorado County (), officially the County of El Dorado, is a county located in the U.S. state of California. As of the 2020 census, the population was 191,185. The county seat is Placerville. The County is part of the Sacramento-Roseville- Arden-Arcade, CA Metropolitan Statistical Area. It is located entirely in the Sierra Nevada, from the historic Gold Country in the western foothills to the High Sierra in the east. El Dorado County's population has grown as Greater Sacramento has expanded into the region. Where the county line crosses US 50 at Clarksville, the distance to Sacramento is 15 miles. In the county's high altitude eastern end at Lake Tahoe, environmental awareness and environmental protection initiatives have grown along with the population since the 1960 Winter Olympics, hosted at the former Squaw Valley Ski Resort in neighboring Placer County. History What is now known as El Dorado County has been home to the Maidu, Nisenan, Washoe, and Miwok Ind ...

California Gold Rush
The California Gold Rush (1848–1855) was a gold rush that began on January 24, 1848, when gold was found by James W. Marshall at Sutter's Mill in Coloma, California. The news of gold brought approximately 300,000 people to California from the rest of the United States and abroad. The sudden influx of gold into the money supply reinvigorated the American economy; the sudden population increase allowed California to go rapidly to statehood, in the Compromise of 1850. The Gold Rush had severe effects on Native Californians and accelerated the Native American population's decline from disease, starvation and the California genocide. The effects of the Gold Rush were substantial. Whole indigenous societies were attacked and pushed off their lands by the gold-seekers, called "forty-niners" (referring to 1849, the peak year for Gold Rush immigration). Outside of California, the first to arrive were from Oregon, the Sandwich Islands (Hawaii) and Latin America in late 1848. ...

1878 Paris Exposition
The third Paris World's Fair, called an Exposition Universelle in French, was held from 1 May to 10 November 1878. It celebrated the recovery of France after the 1870–71 Franco-Prussian War. Construction The buildings and the fairgrounds were somewhat unfinished on opening day, as political complications had prevented the French government from paying much attention to the exhibition until six months before it was due to open. However, efforts made in April were prodigious, and by 1 June, a month after the formal opening, the exhibition was finally completed. This exposition was on a far larger scale than any previously held anywhere in the world. It covered over , the main building in the Champ de Mars and the hill of Chaillot, occupying . The Gare du Champ de Mars was rebuilt with four tracks to receive rail traffic occasioned by the exposition. The Pont d'Iéna linked the two exhibition sites along the central allée. The French exhibits filled one-half of the entir ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Calaveras County, California
Calaveras County (), officially the County of Calaveras, is a county in both the Gold Country and High Sierra regions of the U.S. state of California. As of the 2010 census, the population was 45,292. The county seat is San Andreas. Angels Camp is the county's only incorporated city. ''Calaveras'' is Spanish for "skulls"; the county was reportedly named for the remains of Native Americans discovered by the Spanish explorer Captain Gabriel Moraga. Calaveras Big Trees State Park, a preserve of giant sequoia trees, is in the county several miles east of the town of Arnold on State Highway 4. Credit for the discovery of giant sequoias there is given to Augustus T. Dowd, a trapper who made the discovery in 1852 while tracking a bear. When the bark from the "Discovery Tree" was removed and taken on tour around the world, the trees became a worldwide sensation and one of the county's first tourist attractions. The uncommon gold telluride mineral calaverite was discovered i ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

California State Mining And Mineral Museum
The California State Mining and Mineral Museum is a museum in the state park system of California, United States, home to the state's mineral collection, with minerals and gems from all over the world. The museum also interprets the state's mineral resources and mining heritage. It is located in Mariposa, a city in central California, on the Mariposa County fairgrounds. The museum houses a collection that was created in 1880, with the establishment of the California State Mining Bureau. Henry G. Hanks was the first California State Mineralogist and was tasked with managing the collection. The collection was housed in the ''Ferry Building'' in San Francisco until 1983. The collection opened in its current home at the Mariposa County Fairgrounds in 1986. The collection was transferred from the California Department of Conservation to the California Department of Parks & Recreation in 1999. At present, it is the only California State Park without any associated land. Today, the i ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
