David H. Moffat
David Halliday Moffat (July 22, 1839 – March 18, 1911) was an American financier and industrialist, who was one of the original pioneers of Denver, Colorado. History Moffat was born in Washingtonville, New York, to David and Catherine Gregg. In 1851, when he was twelve years old, he moved to New York City, where he began work as a messenger boy in the New York Exchange Bank, now the Irving Exchange National Bank. His starting position was minor, but he was eager to learn the banking business. Moffat was noticed by the president, and advanced to the position of assistant teller. In 1855 he made his way to Des Moines, Iowa, and became teller in the bank of A. J. Stevens & Company. Moffat then became cashier of the Bank of Nebraska, owned by B. F. Alien, of Des Moines. He moved to Denver, Colorado, in 1860, where he opened a bookstore on 15th and Larimer. The book and stationery store was not highly profitable, so after a few years he went back to banking. On April 17, 1865, the F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Popular Science
Popular science (also called pop-science or popsci) is an interpretation of science intended for a general audience. While science journalism focuses on recent scientific developments, popular science is more broad ranging. It may be written by professional science journalists or by scientists themselves. It is presented in many forms, including books, film and television documentaries, magazine articles, and web pages. History Before the modern specialization and professionalization of science, there was often little distinction between "science" and "popular science", and works intended to share scientific knowledge with a general reader existed as far back as Greek and Roman antiquity. Without these popular works, much of the scientific knowledge of the era might have been lost. For example, none of the original works of the Greek astronomer Eudoxus (4th century BC) have survived, but his contributions were largely preserved due to the didactic poem '' Phenomena'' writte ...

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." Despite its lofty goals, the line never connected itself with the Pacific or any transcontinental line, apart from its terminal at Denver Union Station. 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 Pac ...

Abt Rack System
A rack railway (also rack-and-pinion railway, cog railway, or cogwheel railway) is a steep grade railway with a toothed rack rail, usually between the running rails. The trains are fitted with one or more cog wheels or pinions that mesh with this rack rail. This allows the trains to operate on steep gradients of 100% (45 degrees) or more, well above the 10% maximum for friction-based rail. The rack and pinion mechanism also provides more controlled braking and reduces the effects of snow or ice on the rails. Most rack railways are mountain railways, although a few are transit railways or tramways built to overcome a steep gradient in an urban environment. The first cog railway was the Middleton Railway between Middleton and Leeds in West Yorkshire, England, United Kingdom, where the first commercially successful steam locomotive, ''Salamanca'', ran in 1812. This used a rack and pinion system designed and patented in 1811 by John Blenkinsop. The first mountain cog railway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manitou And Pike's Peak Railway
The Broadmoor Manitou and Pikes Peak Cog Railway (also known as the Pikes Peak Cog Railway) is a cog railway that climbs one of the most iconic mountains in the United States, Pikes Peak in Colorado. The base station is in Manitou Springs, near Colorado Springs. Construction on the line was started in 1889 and the first train reached the summit on June 30, 1891. Cog railways are common in Switzerland and found in other parts of the world (totaling about 50 lines), but this is one of only three such lines remaining in the United States, the others being the older Mount Washington Cog Railway in New Hampshire, and the short Quincy and Torch Lake Cog Railway. Originally powered by steam locomotives, the line later switched over to diesel-powered locomotives and self-propelled railcars. The railway was closed between October 29, 2017 and May 20, 2021, for a complete refurbishment that saw the replacement of the track infrastructure, the rebuild of older railcars and the purchas ...

Denver Tramway
The Denver Tramway, operating in Denver, Colorado, was a streetcar system incorporated in 1886. The tramway was unusual for a number of reasons: the term "tramway" is generally not used in the United States, and it is not known why the company was named as such. The track was Narrow gauge railway, narrow gauge, an unusual gauge in the United States (although streetcars in Los Angeles also used this gauge), but in general use by railways in Japan, southern Africa, New Zealand, and Queensland, Australia. The tramway made use of a variety of types of streetcars, including conduit cars (until 1888), cable car (railway), cable cars (until 1900), and trolley cars (until 1950). At the height of its trolley operations, the tramway owned more than of track and operated over 250 streetcars. By the end of trolley service, only 64 streetcars were still in use. After streetcar operation ceased in 1950 the tramway operated trolleybus, trolley coaches and conventional buses, but continued ...

Denver And New Orleans Railroad
The Denver and New Orleans Railroad (D&NO) was a railroad in Colorado started by Colorado Governor John Evans, along with railroad entrepreneur David Moffat and other associates in 1881. Originally chartered to build a railroad from Denver, Colorado to the Gulf of Mexico, the charter was later changed instead connect southward to the Fort Worth and Denver City Railway which was building northwest from Fort Worth, Texas. After the "completion of the Denver and New Orleans Railroad in July, 1882" from Denver to Pueblo, Colorado—the Denver, Texas and Fort Worth Railroad was organized to build south from the D&NO at Pueblo, Colorado. In 1888 it linked with the FW&DC, and in central Colorado it had a branch to Franceville, Colorado, for coal from the Franceville Mine, and the branch into Colorado Springs from Jimmy Camp station in September 1882 "was renamed Manitou Junction site nownear where US24 and Colorado 94 meet" north of Peterson Air Force Base. The three railroads c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colorado And Southern Railway
The Colorado and Southern Railway was an American Railroad classes#Class I, Class I railroad in the western United States that operated independently from 1898 to 1908, then as part of the Chicago, Burlington and Quincy Railroad until it was absorbed into the Burlington Northern Railroad in 1981. The railway began as the consolidation of bankrupt railroads in 1898. The Colorado Central Railroad and Cheyenne and Northern Railway were brought together to form the Union Pacific, Denver and Gulf Railway in 1890. When Union Pacific went bankrupt in 1893 they were separated from the Union Pacific and united with the Denver, Leadville and Gunnison Railway and others, by Frank Trumbull to form the Colorado and Southern Railroad in 1898. In 1908 the Chicago, Burlington and Quincy Railroad bought control of the C&S. It would later merge into the Burlington Northern Railroad in 1981. At the end of 1970 it operated 692 miles of road on 1116 miles of track; that year it reported of reve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Park (Park County, Colorado)
South Park is a grassland flat within the basin formed by the Rocky Mountains' Mosquito and Rampart Mountain Ranges within central Colorado. This high valley ranges in elevation from approximately 9,000 to 10,000 ft (3,000 m). It encompasses approximately 1,000 square miles (2,590 km2 or 640,000 acres) around the headwaters of the South Platte River in Park County approximately 60 mi (100 km) southwest of Denver. It is the largest and southernmost of three similarly named high elevation basins in the Front Range of Colorado, the others being North Park and Middle Park. The largest town in the basin is Fairplay, with a population of 724. Geology Geologically, the valley is a wide faulted syncline of sedimentary rocks, sitting between the predominantly Precambrian igneous rocks of the Front Range to the east and the Sawatch Uplift to the west. The Mosquito Range forms a high barrier along the western side of the valley. The long-extinct Thirty-Nine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platte Canyon
The Platte Canyon is a deep, narrow, scenic gorge on the South Platte River in the Rocky Mountains of Colorado. The canyon is southwest of Denver in Park County The canyon is at the entrance to the mountains, where the South Platte emerges through the Rampart Range through the hogbacks onto Eastern Plains. The lower narrow section is sometimes called Waterton Canyon, referring to Waterton, Colorado. Geography The term Platte Canyon is used varyingly to apply to the entire section of the South Platte and the North Fork South Platte in the mountains between South Park and the eastern plains. It also is often applied to the communities along the North Fork near Bailey. The narrowest part of the canyon is a remote and roadless gorge (Waterton Canyon) approximately 8 miles (13 km) long, at its lower extremity between the hamlet of South Platte and Kassler, where it emerges from the mountains. In this section, the canyon has walls that rise approximately 1000 ft (30 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colorado Mineral Belt
The Colorado Mineral Belt (CMB) is an area of ore deposits from the La Plata Mountains in Southwestern Colorado to near the middle of the state at Boulder, Colorado, and from which over 25 million troy ounces (778 t) of gold were extracted beginning in 1858. The belt is a "northeast-striking zone defined by: a Proterozoic shear zone system (McCoy, 2001); a suite of Laramide-aged plutons and related ore deposits ( Tweto and Sims, 1963); a major gravity low (Isaacson and Smithson, 1976); low- crustal velocities; and high heat flow (Decker et al., 1988)." Mining districts includ * Central City-Idaho Springs district * Leadville mining district, named for Leadville, Colorado * Sneffels-Red Mountain-Telluride district The belt lies within a zone that has been geologically active at intervals beginning from near the time of crustal accretion in central Colorado at least 1.6 billion years ago until the present. Parts of the CMB follow shear zones of Precambrian age and the Paleozoic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
