The Arizona Mineral Belt Railroad was a nineteenth-century United States company founded by businessman James Ward Eddy in 1881, with the hope of connecting northern and southern Arizona. It did not create a finished railway line before being dissolved.
By the late nineteenth century, the US state of Arizona was experiencing a flush of pioneer development. A railroad line had been laid across northern Arizona by Atchison, Topeka and Santa Fe Railway, connecting that end of the state with national and worldwide opportunities. The southern part of Arizona had also attracted miners to its silver and copper deposits. But it had no direct connection to the nation's railway system, and it was geographically isolated by the southern edge of the Colorado Plateau, an elevated feature that is roughly centered on the Four Corners area of the southwest United States.
A businessman, James Eddy, realized that if a connection between the two areas were available, the northern ponderosa pine forests would help southern Arizona construction projects, which could produce silver and copper to pay for the commerce.
The greatest obstacle to such a railway line was the Mogollon Rim, a half-mile-high escarpment at the edge of the Colorado Plateau. Engineers contracted by Eddy determined that a tunnel of 3,100 feet (945m) length and 16 feet (4.88m) width through this Rim would allow laden trains to access the top of the Plateau. So in 1881, Eddy formed the Arizona Mineral Belt Railway Company, and began seeking investors.
Workers began blasting a tunnel into the Rim in 1883. By the end of the summer the available funds were exhausted but only 70 feet (21m) of tunnel had been completed. Eddy spent the next several years securing additional investment, which was used in laying 35 miles (56 km) of track south of Flagstaff. However, when that additional capital had been expended, Eddy gave up the project.
Over time, the 35 miles of track that were laid south of Flagstaff have been torn up by locals who reused the scrap. The only remaining evidence of Eddy's project is the partially completed tunnel deep in the Tonto National Forest. [1]
The Denver & Rio Grande Western Railroad, often shortened to Rio Grande, D&RG or D&RGW, formerly the Denver & Rio Grande Railroad, was an American Class I railroad company. The railroad started as a 3 ft narrow-gauge line running south from Denver, Colorado, in 1870. It served mainly as a transcontinental bridge line between Denver, and Salt Lake City, Utah. The Rio Grande was also a major origin of coal and mineral traffic.
A transcontinental railroad or transcontinental railway is contiguous railroad trackage, that crosses a continental land mass and has terminals at different oceans or continental borders. Such networks can be via the tracks of either a single railroad or over those owned or controlled by multiple railway companies along a continuous route. Although Europe is crisscrossed by railways, the railroads within Europe are usually not considered transcontinental, with the possible exception of the historic Orient Express. Transcontinental railroads helped open up unpopulated interior regions of continents to exploration and settlement that would not otherwise have been feasible. In many cases they also formed the backbones of cross-country passenger and freight transportation networks. Many of them continue to have an important role in freight transportation and some like the Trans-Siberian Railway even have passenger trains going from one end to the other.
Jerome is a town in the Black Hills of Yavapai County in the U.S. state of Arizona. Founded in the late 19th century on Cleopatra Hill overlooking the Verde Valley, Jerome is located more than 5,000 feet (1,500 m) above sea level. It is about 100 miles (160 km) north of Phoenix along State Route 89A between Sedona and Prescott. Supported in its heyday by rich copper mines, it was home to more than 10,000 people in the 1920s. As of the 2010 census, its population was 444. It is now known for its tourist attractions, such as its "ghost town" status and local wineries.
The Mogollon Rim is a topographical and geological feature cutting across the northern half of the U.S. state of Arizona. It extends approximately 200 miles (320 km), starting in northern Yavapai County and running eastward, ending near the border with New Mexico. It forms the southern edge of the Colorado Plateau in Arizona.
U.S. Route 89 is a north–south United States Numbered Highway with two sections, and one former section. The southern section runs for 848 miles (1,365 km) from Flagstaff, Arizona, to the southern entrance of Yellowstone National Park. The northern section runs for 404 miles (650 km) from the northern entrance of Yellowstone National Park in Montana, ending at the Canadian border. Unnumbered roads through Yellowstone connect the two sections. Before 1992, US 89 was a Canada–Mexico, border-to-border highway that ended at Nogales, Arizona, on its southern end.
The Carson and Colorado Railway was a U.S. 3 ft narrow gauge railroad that ran from Mound House, Nevada, to Keeler, California below the Cerro Gordo Mines. It was incorporated on May 10, 1880 as the Carson and Colorado Railroad, and construction on the railroad began on May 31, 1880. The 3 ft narrow gauge track was chosen to reduce cost. Much of the route now parallels U.S. Route 95 Alternate, U.S. Route 95, Nevada State Route 360, U.S. Route 6, and U.S. Route 395.
The Denver, South Park, and Pacific Railroad was a historic 3 ft 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. 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 the new moniker 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 century, nearly all the company's original lines were dismantled or converted into 4 ft 8+1⁄2 instandard gauge. The last train to run the old DSP&P tracks was from Como, Colorado on April 11, 1937. A section of the standard gauge line between Leadville and Climax is still operated as a passenger excursion railroad called the Leadville, Colorado and Southern Railroad. At its peak the Denver, South Park and Pacific Railroad had 335 miles (539 km) of narrow gauge line, making it the largest narrow gauge railroad in the state of Colorado.
The known human history of the Grand Canyon area stretches back 10,500 years, when the first evidence of human presence in the area is found. Native Americans have inhabited the Grand Canyon and the area now covered by Grand Canyon National Park for at least the last 4,000 of those years. Ancestral Pueblo peoples, first as the Basketmaker culture and later as the more familiar Pueblo people, developed from the Desert Culture as they became less nomadic and more dependent on agriculture. A similar culture, the Cochimi also lived in the canyon area. Drought in the late 13th century likely caused both groups to move on. Other people followed, including the Paiute, Cerbat, and the Navajo, only to be later forced onto reservations by the United States Government.
Tennessee Pass elevation 10,424 ft (3,177 m) is a high mountain pass in the Rocky Mountains of central Colorado in the United States. The pass was named after Tennessee, the native state of a group of early prospectors.
The Georgetown Loop Railroad is a 3 ft narrow gauge United States heritage railroad located in the Rocky Mountains in Clear Creek County, adjacent to Interstate 70 in Colorado.
The Coconino National Forest is a 1.856-million acre United States National Forest located in northern Arizona in the vicinity of Flagstaff. Originally established in 1898 as the "San Francisco Mountains National Forest Reserve", the area was designated a U.S. National Forest in 1908 when the San Francisco Mountains National Forest Reserve was merged with lands from other surrounding forest reserves to create the Coconino National Forest. Today, the Coconino National Forest contains diverse landscapes, including deserts, ponderosa pine forests, flatlands, mesas, alpine tundra, and ancient volcanic peaks. The forest surrounds the towns of Sedona and Flagstaff and borders four other national forests; the Kaibab National Forest to the west and northwest, the Prescott National Forest to the southwest, the Tonto National Forest to the south, and the Apache-Sitgreaves National Forest to the southeast. The forest contains all or parts of ten designated wilderness areas, including the Kachina Peaks Wilderness, which includes the summit of the San Francisco Peaks. The headquarters are in Flagstaff. There are local ranger district offices in Flagstaff, Happy Jack, and Sedona.
The Colorado and Southern Railway was an American 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 Treffry Tramways were a group of mineral tramways in Cornwall in the United Kingdom, constructed by Joseph Treffry (1782-1850), a local land owner and entrepreneur. They were constructed to give transport facilities to several mines and pits producing non-ferrous metal, granite and china clay in the area between the Luxulyan Valley and Newquay, and were horse-operated, with the use of water and steam power on inclines, and at first operated in conjunction with the Par Canal and Par Docks, also constructed by Treffry. One of the routes crossed the Luxulyan Valley on a large viaduct, the largest in Cornwall when it was built.
The transportation system of Arizona comprises car, rail, air, bus, and bicycle transport.
Arizona is a landlocked state situated in the southwestern region of the United States of America. It has a vast and diverse geography famous for its deep canyons, high- and low-elevation deserts, numerous natural rock formations, and volcanic mountain ranges. Arizona shares land borders with Utah to the north, the Mexican state of Sonora to the south, New Mexico to the east, and Nevada to the northwest, as well as water borders with California and the Mexican state of Baja California to the southwest along the Colorado River. Arizona is also one of the Four Corners states and is diagonally adjacent to Colorado.
The Black Hills of Yavapai County are a large mountain range of central Arizona in southeast Yavapai County. It is bordered by the Verde Valley to the east. The northwest section of the range is bisected from the southeast section by Interstate 17, which is the main route connecting Phoenix to Sedona, Oak Creek Canyon, and Flagstaff. This bisection point is the approximate center of the mostly northwest by southeast trending range. The northwest section contains a steep escarpment on the northeast with the Verde Valley, the escarpment being the location of the fault-block that created the historic mining district at Jerome. The United Verde Mine was one of the largest copper mines in the United States, producing large quantities of copper, gold, silver and zinc.
Aztec Land and Cattle Company, Limited ("Aztec") is a land company with a historic presence in Arizona. It was formed in 1884 and incorporated in early 1885 as a cattle ranching operation that purchased 1,000,000 acres in northern Arizona from the Atlantic & Pacific Railroad. It then imported approximately 32,000 head of cattle from Texas and commenced ranching operations in Arizona. Because Aztec's brand was the Hashknife, a saddler's knife used on early day ranches, the company was known more famously as The Hashknife Outfit. The company has been in continuous existence since 1884.
The United Verde and Pacific Railway was a 3 ft narrow gauge railroad that operated from 1895 to 1920 in what became Yavapai County in the U.S. state of Arizona. William A. Clark built the 26-mile (42 km) line to link his copper mine and smelter in Jerome to an existing branch of the Santa Fe Railway system. Clark eventually replaced the line with three 4 ft 8+1⁄2 instandard gauge rail lines after building a new smelter and company town in Clarkdale.
The geology of Arizona began to form in the Precambrian. Igneous and metamorphic crystalline basement rock may have been much older, but was overwritten during the Yavapai and Mazatzal orogenies in the Proterozoic. The Grenville orogeny to the east caused Arizona to fill with sediments, shedding into a shallow sea. Limestone formed in the sea was metamorphosed by mafic intrusions. The Great Unconformity is a famous gap in the stratigraphic record, as Arizona experienced 900 million years of terrestrial conditions, except in isolated basins. The region oscillated between terrestrial and shallow ocean conditions during the Paleozoic as multi-cellular life became common and three major orogenies to the east shed sediments before North America became part of the supercontinent Pangaea. The breakup of Pangaea was accompanied by the subduction of the Farallon Plate, which drove volcanism during the Nevadan orogeny and the Sevier orogeny in the Mesozoic, which covered much of Arizona in volcanic debris and sediments. The Mid-Tertiary ignimbrite flare-up created smaller mountain ranges with extensive ash and lava in the Cenozoic, followed by the sinking of the Farallon slab in the mantle throughout the past 14 million years, which has created the Basin and Range Province. Arizona has extensive mineralization in veins, due to hydrothermal fluids and is notable for copper-gold porphyry, lead, zinc, rare minerals formed from copper enrichment and evaporites among other resources.
