Cheyenne, Wyoming in the context of "Laramie Mountains"

The Front Range Urban Corridor is an oblong region of urban population located along the eastern face of the Southern Rocky Mountains, encompassing 18 counties in the US states of Colorado and Wyoming. The corridor derives its name from the Front Range, the mountain range that defines the western boundary of the corridor which serves as a gateway to the Rocky Mountains. The region comprises the northern portion of the Southern Rocky Mountain Front geographic area, which in turn comprises the southern portion of the Rocky Mountain Front geographic area of Canada and the United States. The Front Range Urban Corridor had a population of 5,055,344 at the 2020 census, an increase of +16.65% since the 2010 census, and an estimated population of 5,226,455 as of 2024 census estimates.

The corridor contains some of the West's largest cities, such as Denver and Colorado Springs. It also contains smaller cities such as Pueblo and Cheyenne. Its main transportation corridor is Interstate 25. There have been many proposals for Front Range Passenger Rail. None have come to fruition as of 2021, though plans are under development.

Wyoming (/waɪˈoʊmɪŋ/ wye-OH-ming) is a landlocked state in the Mountain West subregion of the Western United States. It borders Montana to the north and northwest, South Dakota and Nebraska to the east, Idaho to the west, Utah to the southwest, and Colorado to the south. With an estimated population of 587,618 as of 2024, Wyoming is the least populous state despite being the tenth-largest by area, and it has the second-lowest population density after Alaska. The state capital and most populous city is Cheyenne, which had a population of 65,132 in 2020.

Wyoming's western half consists mostly of the ranges and rangelands of the Rocky Mountains; its eastern half consists of high-elevation prairie, and is referred to as the High Plains. Wyoming's climate is semi-arid in some parts and continental in others, making it drier and windier overall than other states, with greater temperature extremes. The federal government owns just under half of Wyoming's land, generally protecting it for public use. The state ranks sixth in the amount of land—and fifth in the proportion of its land—that is owned by the federal government. Its federal lands include two national parks (Grand Teton and Yellowstone), two national recreation areas, two national monuments, and several national forests, as well as historic sites, fish hatcheries, and wildlife refuges.

Laramie County is a county located at the southeast corner of the state of Wyoming. As of the 2020 United States census, the population was 100,512 or 17.4% of the state's total 2020 population, making it the most populous county in Wyoming, but the least populous county in the United States to be the most populous in its state. The county seat is Cheyenne, the state capital. The county lies west of the Nebraska state line and north of the Colorado state line. Laramie County comprises the Cheyenne, WY Metropolitan Statistical Area. The city of Laramie, Wyoming, is in neighboring Albany County.

The Diocese of Cheyenne (Latin: Dioecesis Cheyennensis) is a Latin Church ecclesiastical territory, or diocese, of the Catholic Church in the state of Wyoming in the United States. It is a suffragan diocese in the ecclesiastical province of the metropolitan Archdiocese of Denver.

The cathedral and mother church for the Diocese of Cheyenne is St. Mary's Cathedral, located in Cheyenne, Wyoming. The diocese covers all of Wyoming, as well as the parts of Yellowstone National Park in Montana and Idaho.

The 1977 Russian flu was an influenza pandemic that was first reported by the Soviet Union in 1977 and lasted until 1979. The outbreak in northern China started in May 1977, slightly earlier than that in the Soviet Union. The pandemic mostly affected a population younger than 25 or 26 years of age, and was described as mild. It was caused by an H1N1 flu strain which highly resembled a virus strain circulating worldwide from 1946 to 1957. Genetic analysis and several unusual characteristics of the 1977 Russian flu have prompted many researchers to say that the virus was released to the public through a laboratory accident, or resulted from a live-vaccine trial escape.

The Russian flu first reached the United Kingdom in 1977, and the United States in January 1978. The first outbreak in the United States took place in Cheyenne, Wyoming, but more than 70% of those infected were students. The flu spread in schools and military bases throughout the United States, but most of those infected were below the age of 26. In the United States, the death rate in affected individuals was low.

The South Platte River (Sioux: Wašíŋ-Wakpá [waˈʃĩ wakˈpa] lit. “bison tallow river”) is one of the two principal tributaries of the Platte River. Flowing through the U.S. states of Colorado and Nebraska, it is itself a major river of the American Midwest and the American Southwest/Mountain West. Its drainage basin includes much of the eastern flank of the Rocky Mountains in Colorado, much of the populated region known as the Colorado Front Range and Eastern Plains, and a portion of southeastern Wyoming in the vicinity of the city of Cheyenne. It joins the North Platte River in western Nebraska to form the Platte, which then flows across Nebraska to the Missouri. The river serves as the principal source of water for eastern Colorado. In its valley along the foothills in Colorado, it has permitted agriculture in an area of the Colorado Piedmont and Great Plains that is otherwise arid.

Interstate 25 (I-25), also known as the Pan-American Freeway, is a major Interstate Highway in the western United States. It is primarily a north–south highway, serving as the main route through New Mexico, Colorado, and Wyoming. I-25 stretches from I-10 at Las Cruces, New Mexico (approximately 25 miles [40 km] north of El Paso, Texas) to I-90 in Buffalo, Wyoming (approximately 60 miles [97 km] south of the Montana–Wyoming border). It passes through or near Albuquerque, New Mexico; Pueblo, Colorado Springs, and Denver in Colorado; and Cheyenne and Casper in Wyoming. The I-25 corridor is mainly rural, especially in Wyoming, excluding the Albuquerque metropolitan area and the Front Range urban corridor from Pueblo to Cheyenne.

The part of I-25 in Colorado passes just east of the Front Range of the Rocky Mountains. That stretch was involved in a large-scale renovation named the Transportation Expansion (T-REX) Project in Denver and the Colorado Springs Metropolitan Interstate Expansion (COSMIX). These projects, and others in New Mexico, were necessary because these stretches of I-25 were originally inadequately designed and constructed (the pavement was deteriorating rapidly) and also because urban areas, like Albuquerque, Colorado Springs, and Denver, had tripled and quadrupled in population much earlier than anyone had anticipated back in the 1950s and 1960s. Major highway work for the T-REX project ended on August 22, 2006. The COSMIX project was completed in December 2007. Several other smaller improvement projects for I-25 are still ongoing within New Mexico and Colorado.

Front Range Passenger Rail is a proposed intercity passenger train service along the Front Range and broader I-25 corridors in Colorado and Wyoming. Most proposals envision a route from Pueblo north to Colorado Springs, Denver, Boulder, and Fort Collins. Extensions north to Cheyenne and south to Trinidad, Albuquerque, and even El Paso have been discussed.

Front Range communities were historically connected by rail transit until the mid-20th century. A series of studies performed since the early 2000s have shown mounting interest in renewed service. In the 2020s, Colorado created a taxing district to fund a new passenger-rail effort, while Amtrak included the route in its expansion vision.

Union Pacific 4014 is a preserved 4884-1 class 4-8-8-4 "Big Boy" type steam locomotive owned and operated by the Union Pacific as part of its heritage fleet. Built in November 1941 by the American Locomotive Company in Schenectady, New York, it was assigned to haul heavy freight trains in the Wasatch mountain range. The locomotive was retired from revenue service on December 7, 1961, and was donated to the Railway & Locomotive Historical Society; thereafter, it was displayed in Fairplex at the RailGiants Train Museum in Pomona, California.

In 2013, UP re-acquired the locomotive and launched a restoration project at its Steam Shop in Cheyenne, Wyoming. In May 2019, No. 4014 moved under its own power after sitting dormant for almost six decades, becoming the world's largest operational steam locomotive and the only operating Big Boy locomotive of the eight that remain in existence. It now operates in excursion service for the UP steam program. No. 4014 became the first mainline steam locomotive to be equipped with the positive train control system in 2021.
