Trout Creek Pass
Trout Creek Pass, elevation , is a mountain pass located in the Rocky Mountains of south-central Colorado in the United States. The pass sits atop the southern end of the Mosquito Range on the Park- Chaffee county line, between South Park (the headwaters of the South Platte River to the east) and the headwaters of the Arkansas River to the west. It is traversed jointly by U.S. Highway 24 (US 24) (between Hartsel and Buena Vista) and US 285 (between Fairplay and Buena Vista). It is passable by most motorized vehicles and is closed only during severe winter storms. The approach from the north is mild, while the south side has a moderate 5% grade. Curiously, the elevation stated on the highway sign at the summit (see attached picture) appears to be in error by about , as it disagrees with well-established topographic maps as well as published data. Geologically, the pass is located on a fault that runs along the Mosquito Range. Road cuts along the eastern approac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

Pennsylvanian (geology)
The Pennsylvanian ( , also known as Upper Carboniferous or Late Carboniferous) is, in the International Commission on Stratigraphy, ICS geologic timescale, the younger of two period (geology), subperiods (or upper of two system (stratigraphy), subsystems) of the Carboniferous Period. It lasted from roughly . As with most other geochronology, geochronologic units, the stratum, rock beds that define the Pennsylvanian are well identified, but the exact date of the start and end are uncertain by a few hundred thousand years. The Pennsylvanian is named after the U.S. state of Pennsylvania, where the coal-productive beds of this age are widespread. The division between Pennsylvanian and Mississippian (geology), Mississippian comes from North American stratigraphy. In North America, where the early Carboniferous beds are primarily marine limestones, the Pennsylvanian was in the past treated as a full-fledged geologic period between the Mississippian and the Permian. In parts of Europe, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Colorado Midland
The Colorado Midland Railway , Railway Equipment and Publication CompanyThe Official Railway Equipment Register June 1917, p. 786 incorporated in 1883, was the first standard gauge railroad built over the Continental Divide in Colorado. It ran from Colorado Springs to Leadville and through the divide at Hagerman Pass to Glenwood Springs and Grand Junction. History John J. Hagerman gained control of the Colorado Midland Railway Company in June 1885. In September 1890, Hagerman sold the railroad to the Atchison, Topeka and Santa Fe Railway, which operated the railroad as a subsidiary and changed the name to the Colorado Midland Railroad. For a short time the railroad was consolidated with the Aspen Short Line (1893-1897). Following the Panic of 1893, the Santa Fe railroad failed and both it and the Colorado Midland went into receivership. During this time, a crash in the price of silver also led to economic decline in the mining towns served by the railway. After the c ...

Colorado Silver Boom
The Colorado Silver Boom was a dramatic expansionist period of silver mining activity in the U.S. state of Colorado in the late 19th century. The boom started in 1879 with the discovery of silver at Leadville. Over 82 million dollars worth of silver was mined during the period, making it the second great mineral boom in the state, and coming 20 years after the earlier and shorter Colorado Gold Rush of 1859. The boom was largely the consequence of large-scale purchases of silver by the United States Government authorized by Congress in 1878. The boom endured throughout the 1880s, resulting in an intense increase in both the population and wealth of Colorado, especially in the mountains. It came to an end in 1893 in the wake of the collapse of silver prices caused by the repeal of Sherman Silver Purchase Act.Voynick, S.M., 1992, Colorado Gold, Missoula: Mountain Press Publishing Company, Silver had been discovered in Colorado in the 1860s, with early mining in Clear Creek Canyon at ...

Denver, South Park And Pacific Railroad
The Denver, South Park, and Pacific Railroad (later called the Denver, Leadville and Gunnison Railway) was a historic narrow gauge railroad that operated in Colorado in the western United States in the late 19th century. The railroad opened up the first rail routes to a large section of the central Colorado mining district in the decades of the mineral boom. The railroad took its name from the fact that its main line from Denver ascended the Platte Canyon and traversed South Park, hence its popular name "The South Park Line." Founded in 1872 by Colorado Governor John Evans, the company was purchased by the Union Pacific Railway in 1880, though it continued to be operated independently. The line went bankrupt in 1889 and was reorganized under a new corporate name as the Denver, Leadville and Gunnison Railway. When the Union Pacific went bankrupt in 1893, the DL&G lines went into receivership and were eventually sold to the Colorado and Southern Railway. In the first half of the 20th ...

Paleozoic
The Paleozoic (or Palaeozoic) Era is the earliest of three geologic eras of the Phanerozoic Eon. The name ''Paleozoic'' ( ;) was coined by the British geologist Adam Sedgwick in 1838 by combining the Greek words ''palaiós'' (, "old") and ''zōḗ'' (), "life", meaning "ancient life" ). It is the longest of the Phanerozoic eras, lasting from , and is subdivided into six geologic periods (from oldest to youngest): # Cambrian # Ordovician # Silurian # Devonian # Carboniferous # Permian The Paleozoic comes after the Neoproterozoic Era of the Proterozoic Eon and is followed by the Mesozoic Era. The Paleozoic was a time of dramatic geological, climatic, and evolutionary change. The Cambrian witnessed the most rapid and widespread diversification of life in Earth's history, known as the Cambrian explosion, in which most modern phyla first appeared. Arthropods, molluscs, fish, amphibians, reptiles, and synapsids all evolved during the Paleozoic. Life began in the ocean ...
