Kobuk River Stampede
The Kobuk River Stampede was a brief gold rush on the Kobuk River in Alaska. From 1897 to 1898, several false accounts of the discovery of gold on the Kobuk led nearly 2,000 gold seekers to the area. Most of these prospectors arrived by ship, during the spring of 1898, from the West Coast of North America. The gold rush was brief, with its peak from 1898 to 1899, for local people spread the word upon arrival that no gold was to be found. Out of these 2,000 people, only 800 remained to search; and despite their efforts, only small amounts of placer and lode gold were discovered on a few of the Kobuk's tributaries. Other than the gold deposits, copper, asbestos and lead were also found. Because of the disappointingly small amount of gold, most of the prospectors left soon, some bound for other gold strikes at Nome and the Koyukuk River. Even though the area still produces some placer gold, the gold rush did not notably affect the economy and development of the area. See also *Gol ...

Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gold Mining In Alaska
Gold mining in Alaska, a state of the United States, has been a major industry and impetus for exploration and settlement since a few years after the United States acquired the territory in 1867 from the Russian Empire. Russian explorers discovered placer gold in the Kenai River in 1848, but no gold was produced. Gold mining started in 1870 from placers southeast of Juneau, Alaska. Gold occurs and has been mined throughout Alaska; except in the vast swamps of the Yukon Flats, and along the North Slope between the Brooks Range and the Beaufort Sea. Areas near Fairbanks and Juneau, and Nome have produced most of Alaska's historical output and provide all current gold production . Nearly all of the large and many of the small placer-gold mines currently operating in the US are in Alaska. Seven modern large-scale hard-rock mines operated in Alaska ; five were gold-producing mines. There are also small-scale hard-rock gold-mining operations. In 2019 Alaska produced 539,390 troy ounc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Koyukuk River
The Koyukuk River (; ''Ooghekuhno' '' in Koyukon, ''Kuuyukaq'' or ''Tagraġvik'' in Iñupiaq) is a tributary of the Yukon River, in the U.S. state of Alaska. It is the last major tributary entering the Yukon before the larger river empties into the Bering Sea. Rising at the confluence of the North Fork Koyukuk River with the Middle Fork Koyukuk River, it flows generally southwest to meet the larger Yukon River at Koyukuk. The river, with headwaters above the Arctic Circle in the Endicott Mountains of the Brooks Range, drains an area north of the Yukon River that includes part of the Gates of the Arctic National Park and Preserve, as well as Kanuti National Wildlife Refuge and Koyukuk National Wildlife Refuge. The main stem of the river is lined by the communities of Evansville, Bettles, Alatna, Allakaket, Hughes, and Huslia before reaching Koyukuk. Its headwaters tributaries include the Koyukuk's south, middle, and north forks, the Alatna River, and the John River.Benke an ...

Nome, Alaska
Nome (; ik, Sitŋasuaq, ) is a city in the Nome Census Area in the Unorganized Borough of Alaska, United States. The city is located on the southern Seward Peninsula coast on Norton Sound of the Bering Sea. It had a population of 3,699 recorded in the 2020 census, up from 3,598 in 2010. Nome was incorporated on April 9, 1901, and was once the most-populous city in Alaska. Nome lies within the region of the Bering Straits Native Corporation, which is headquartered in Nome. The city of Nome also claims to be home to the world's largest gold pan, although this claim has been disputed by the Canadian city of Quesnel, British Columbia. In the winter of 1925, a diphtheria epidemic raged among Alaska Natives in the Nome area. Fierce territory-wide blizzard conditions prevented the delivery of a life-saving diphtheria antitoxin serum by airplane from Anchorage. A relay of dog sled teams was organized to deliver the serum. Today, the Iditarod Dog Sled Race follows the same route they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asbestos
Asbestos () is a naturally occurring fibrous silicate mineral. There are six types, all of which are composed of long and thin fibrous crystals, each fibre being composed of many microscopic "fibrils" that can be released into the atmosphere by abrasion and other processes. Inhalation of asbestos fibres can lead to various dangerous lung conditions, including mesothelioma, asbestosis, and lung cancer, so it is now notorious as a serious health and safety hazard. Archaeological studies have found evidence of asbestos being used as far back as the Stone Age to strengthen ceramic pots, but large-scale mining began at the end of the 19th century when manufacturers and builders began using asbestos for its desirable physical properties. Asbestos is an excellent electrical insulator and is highly fire-resistant, so for much of the 20th century it was very commonly used across the world as a building material, until its adverse effects on human health were more widely acknowledged ...

Gold Rush
A gold rush or gold fever is a discovery of gold—sometimes accompanied by other precious metals and rare-earth minerals—that brings an onrush of miners seeking their fortune. Major gold rushes took place in the 19th century in Australia, New Zealand, Brazil, Chile, South Africa, the United States, and Canada while smaller gold rushes took place elsewhere. In the 19th century, the wealth that resulted was distributed widely because of reduced migration costs and low barriers to entry. While gold mining itself proved unprofitable for most diggers and mine owners, some people made large fortunes, and merchants and transportation facilities made large profits. The resulting increase in the world's gold supply stimulated global trade and investment. Historians have written extensively about the mass migration, trade, colonization, and environmental history associated with gold rushes. Gold rushes were typically marked by a general buoyant feeling of a "free-for-all" in income mob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Lode 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 tetrachloroaurate anion. Gold ...
