Aspen Mountain (Colorado)
Aspen Mountain is a mountain summit in the Elk Mountains range of the Rocky Mountains of North America. The peak is located in White River National Forest, south-southeast ( bearing 162°) of downtown Aspen in Pitkin County, Colorado, United States. The north face of the mountain is the location of the Aspen Mountain ski area, one of four adjacent ski areas operated collectively as Aspen/Snowmass. Mountain Aspen Mountain is not particularly high, relative to other mountains in Colorado, but nonetheless looms over the town of Aspen because of the proximity of the town, which was founded as a silver mining camp in 1879 during the Colorado Silver Boom. The mountain flank was the site of intense mining activity in the late 1880s and early 1890s, with many remains of mining activity below and on the surface of the mountain. In the middle 20th century it became the site of recreational downhill skiing. In 1946, the newly formed Aspen Skiing Company, founded by Walter Paepcke, ...

Sea Level Datum Of 1929
The National Geodetic Vertical Datum of 1929 is the official name since 1973 of the vertical datum established for vertical control surveying in the United States, United States of America by the General Adjustment of 1929. Originally known as Sea Level Datum of 1929, NGVD 29 was determined and published by the United States Coast and Geodetic Survey and used to measure the elevation of a point above and Depression (geology), depression below mean sea level (MSL). NGVD29 was superseded by the North American Vertical Datum of 1988 (NAVD 88), based upon reference to a single benchmark (referenced to the new International Great Lakes Datum of 1985 local mean sea level height value), although many cities and U.S. Army Corps of Engineers "legacy" projects with established data continued to use the older datum. Methodology Mean sea level was measured at 26 tide gauges: 21 in the United States and five in Canada. The datum was defined by the observed heights of mean sea level at the ...

Silver
Silver is a chemical element; it has Symbol (chemistry), symbol Ag () and atomic number 47. A soft, whitish-gray, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Silver is found in the Earth's crust in the pure, free elemental form ("native metal, 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 (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, 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. Other than in currency and as an in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Pitkin County, Colorado
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains te ...

List Of The Most Prominent Summits Of Colorado
The following sortable table comprises the 100 most topographically prominent mountain peaks of the U.S. State of Colorado. Topographic elevation is the vertical distance above the reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface. The topographic prominence of a summit is the elevation difference between that summit and the highest or key col to a higher summit. The topographic isolation of a summit is the minimum great-circle distance to a point of equal elevation. This article defines a significant summit as a summit with at least of topographic prominence, and a major summit as a summit with at least of topographic prominence. An ultra-prominent summit is a summit with at least of topographic prominence. There are 126 ultra-prominent summits in the United States. All elevations include an adjustment from the National Geodetic Vertical Datum of 1929 ( NGVD 29) to the North American Vertical Datum of 1988 ( ...

Aspen Times
''The Aspen Times'' is a free, 6,500-circulation daily newspaper in the ski resort town of Aspen, Colorado, United States, with a history dating back to 1881. History The Aspen Weekly Times' first issue was published April 23, 1881 when Aspen was a silver mining town, and the purpose of the newspaper was to bring news about the outside world to miners. The original owner was D.H. Waite & Co under the leadership of Davis Hanson Waite who sold the paper to B. Clark Wheeler in 1885 and later became Governor of Colorado. Within months, Wheeler converted the paper into a daily. Wheeler was a promoter and had various business interests. In 1880, Wheeler changed the name of the city from Ute City to Aspen. In the 1890s, the paper returned to a weekly publication schedule as the population of Aspen dropped due to the bust in silver prices. In 1956, Bil Dunaway, a U.S. Army 10th Mountain Division veteran, bought The Aspen Times, and over the next 35 years would amass a local media empi ...

Chairlift
An elevated passenger ropeway, or chairlift, is a type of aerial lift, which consists of a continuously circulating steel wire rope loop strung between two end terminals and usually over intermediate towers. They are the primary on-hill transport at most ski areas (in such cases referred to as 'ski lifts'), but are also found at amusement parks and various tourist attractions. Depending on carrier size and loading efficiency, a passenger ropeway can move up to 4,000 people per hour, and the fastest lifts achieve operating speeds of up to or . The two-person double chair, which for many years was the workhorse of the ski industry, can move roughly 1,200 people per hour at rope speeds of up to . The four person detachable chairlift ("high-speed quad") can transport 2,400 people per hour with an average rope speed of . Some bi- and tri-cable elevated ropeways and reversible tramways achieve much greater operating speeds. Design and function A chairlift consists of numerous c ...
