Preston, Colorado
Preston is a ghost town in Summit County, Colorado. It is located east of modern Breckenridge, between Jessie mine in Gold Run Gulch and the Jumbo mine. Description Preston is situated above Gold Run Gulch along Dry Gulch Road. The townsite is now National Forest property and is managed by the Breckenridge Heritage Alliance. About west of the townsite are the remains of the Jumbo mine–consisting of abandoned minecarts, several mounds of tailings, and a few largely collapsed wooden structures. The remaining Preston town structures are scattered along a short stretch of road. The Jessie mine is located roughly below Preston and is connected by the road. There is another, unrelated mine named "Jumbo" that operated in the 1910s–roughly 30 years after the opening of the Preston Jumbo mine–near Montezuma several miles to the northeast. In the summer, the town is accessible by bike, car, and foot. In the winter can be reached by cross-country skis, snowshoes, and fatbike ...

Tailings
In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different to overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containing the ore and then relies on chemical reactions to concentrate the sought-after material. In the latter, the extraction of minerals from ore requires comminution, i.e., grinding the ore into fine particles to facilitate extraction of the target element(s). Because of this comminution, tailings consist of a slurry of fine particles, ranging from the size of a grain of sand to a few micrometres. Mine tailings are usually produced from the mill in slurry form, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Millinery
Hat-making or millinery is the design, manufacture and sale of hats and other headwear. A person engaged in this trade is called a milliner or hatter. Historically, milliners, typically women shopkeepers, produced or imported an inventory of garments for men, women, and children and sold these garments in their millinery shop. Many milliners worked as both milliner and fashion designer, such as Rose Bertin, Jeanne Lanvin, and Coco Chanel. The millinery industry benefited from industrialization during the nineteenth century. In 1889 in London and Paris, over 8,000 women were employed in millinery, and in 1900 in New York, some 83,000 people, mostly women, were employed in millinery. Though the improvements in technology provided benefits to milliners and the whole industry, essential skills, craftsmanship, and creativity are still required. Since the mass-manufacturing of hats began, the term milliner is usually used to describe a person who applies traditional hand-craftsmanshi ...

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] |
Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It ...

Silver
Silver is a chemical element with the symbol Ag (from the Latin ', derived from the Proto-Indo-European ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures.

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 an ...

Post Office
A post office is a public facility and a retailer that provides mail services, such as accepting letters and parcels, providing post office boxes, and selling postage stamps, packaging, and stationery. Post offices may offer additional services, which vary by country. These include providing and accepting government forms (such as passport applications), and processing government services and fees (such as road tax, postal savings, or bank fees). The chief administrator of a post office is called a postmaster. Before the advent of postal codes and the post office, postal systems would route items to a specific post office for receipt or delivery. During the 19th century in the United States, this often led to smaller communities being renamed after their post offices, particularly after the Post Office Department began to require that post office names not be duplicated within a state. Name The term "post-office" has been in use since the 1650s, shortly after the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dillon Reservoir
Dillon Reservoir, sometimes referred to as Lake Dillon, is a large fresh water reservoir located in Summit County, Colorado, United States, south of I-70 and bordered by the towns of Frisco, Silverthorne, and Dillon. It is a reservoir for the city of Denver, and its waters are under the control of Denver Water. Popular ski areas are close to the reservoir, including Copper Mountain, Keystone, Arapahoe Basin, and Breckenridge. History In 1859, a large party of gold-seekers led by Ruben Spalding discovered gold near the headwaters of the Blue River, which prompted a population surge in Summit County, Colorado. By October 1859, nearly 100 miners had camped along the river. By 1880, the human population of Summit county had swelled to 5,459. In 1881, Dillon Mining Company patented a 320-acre parcel and divided it into lots to establish the trade-post town of Dillon along the northeast bank of the Snake River, which is part of what was then called Blue River Valley. The town ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frisco, Colorado
Frisco is a home rule municipality located in Summit County, Colorado, United States. The town population was 2,913 at the 2020 United States Census. Frisco is a part of the Breckenridge, CO Micropolitan Statistical Area. It is a popular town among skiers from around the world. Four major ski resorts are located in close proximity to Frisco: Copper Mountain, Breckenridge, Keystone, and Arapahoe Basin. History Frisco was founded by Henry Recen, in 1873, and was built because of the Colorado Silver Boom, which began in 1879. Frisco was incorporated in 1880. The town's name does not come from the popular nickname for the city of San Francisco, California, but is rather named after the popular Frisco Lines Railroad in hopes of it bringing the rail line to the town. Geography At the 2020 United States Census, the town had a total area of including of water. Frisco is located along the coast Lake Dillon, a reservoir constructed between 1961 and 1963 that now covers the original to ...

Fatbike
A fatbike (also called fat bike, fat tire, fat-tire bike, or snow bike) is an off-road bicycle with oversized tires, typically or larger and rims or wider, designed for low ground pressure to allow riding on soft, unstable terrain, such as snow, sand, bogs and mud. Fatbikes are built around frames with wide forks and stays to accommodate the wide rims required to fit these tires. The wide tires can be used with inflation pressures as low as to allow for a smooth ride over rough obstacles. A rating of is suitable for the majority of riders. Fatbikes were invented for use in snow and sand, but are capable of traversing diverse terrain types including snow, sand, desert, bogs, mud, pavement, or traditional mountain biking trails. The sport is sometimes referred to as fatbiking or fat-tire biking. History Although early versions of fat-tired bikes were probably built on a limited basis as long ago as the early 1900s, the first modern versions were not developed until the 1980s. ...

Snowshoeing
Snowshoes are specialized outdoor gear for walking over snow. Their large footprint spreads the user's weight out and allows them to travel largely on top of rather than through snow. Adjustable bindings attach them to appropriate winter footwear. Traditional snowshoes have a hardwood frame filled in with rawhide latticework. Modern snowshoes are made of lightweight metal, plastic, and other synthetic materials. In the past, snowshoes were essential equipment for anyone dependent on travel in deep and frequent snowfall, such as fur trappers. They retain that role in areas where motorized vehicles cannot reach or are inconvenient to use. However, their greatest contemporary use is for recreation. Snowshoeing is easy to learn and in appropriate conditions is a relatively safe and inexpensive recreational activity. However, doing so in icy, steep terrain requires both advanced skill and mountaineering-style pivoting-crampon snowshoes. Development Origins Before people buil ...
