As of 2014, the population was growing slightly with the most growth in tourist-oriented areas, such as Teton County . Boom conditions in neighboring states, such as North Dakota , were drawing energy workers away. About half of Wyoming's counties showed population loss. The state makes active efforts through Wyoming Grown, an internet-based recruitment program, to find jobs for young people educated in Wyoming who have emigrated but may wish to return. The mineral-extraction industry and travel and tourism sector are

484-696: A bill to Congress to provide a "temporary government for the territory of Wyoming ". The territory was named after the Wyoming Valley in Pennsylvania. Thomas Campbell wrote his 1809 poem " Gertrude of Wyoming ", inspired by the Battle of Wyoming in the American Revolutionary War .

Mexico surrendered its northern territory to the U.S. with the Treaty of Guadalupe Hidalgo after the war in 1848; this included much of the western and southern areas of Colorado. Most American settlers first traveled to Colorado through the Santa Fe Trail , which connected the U.S. to Santa Fe and

Poor labor conditions and discontent among miners resulted in several major clashes between strikers and the Colorado National Guard , including the 1903–1904 Western Federation of Miners Strike and Colorado Coalfield War , the latter of which included the Ludlow massacre that killed a dozen women and children. Both

1331-494: A return from Astoria , Robert Stuart and a party of five men discovered South Pass in 1812. The Oregon Trail later followed that route as emigrants moved to the west coast. In 1850, mountain man Jim Bridger first documented what is now known as Bridger Pass . Bridger also explored Yellowstone, and filed reports on the region that, like Colter's, were largely regarded at the time as tall tales . The Union Pacific Railroad constructed track through Bridger Pass in 1868. It

Once government-sponsored expeditions to the Yellowstone country began, Colter's and Bridger's descriptions of the region's landscape were confirmed. In 1872, Yellowstone National Park was created as the world's first, to protect this area. Nearly all of

1573-636: A significant portion of the extreme weather occurs in the least populated areas of the state. Thunderstorms are common east of the Continental Divide in the spring and summer, yet are usually brief. Hail is a common sight in the mountains east of the Divide and across the eastern Plains, especially the northeast part of the state. Hail is the most commonly reported warm-season severe weather hazard, and occasionally causes human injuries, as well as significant property damage. The eastern Plains are subject to some of

1936-543: Is a dry state with much of the land receiving less than 10 inches (250 mm) of rainfall per year. Precipitation depends on elevation with lower areas in the Big Horn Basin averaging 5–8 inches (130–200 mm), making the area nearly a true desert . The lower areas in the North and on the eastern plains typically average around 10–12 inches (250–300 mm), making the climate there semi-arid . Some mountain areas do receive

In south-central Colorado is the large San Luis Valley , where the headwaters of the Rio Grande are located. The northern part of the valley is the San Luis Closed Basin , an endorheic basin that helped created the Great Sand Dunes . The valley sits between the Sangre de Cristo Mountains and San Juan Mountains . The Rio Grande drains due south into New Mexico, Texas, and Mexico. Across

2541-536: Is found along the ecotone , or transition zone, between the Great Plains to the east and the sagebrush steppe to the west, and occurs across a gradient of temperature, precipitation, and elevation. As with grasslands in the Great Plains, the Thunder Basin evolved with disturbance from drought, grazing, fire and burrowing mammals. Burrowing mammals play a functional role in the grasslands. Prairie dogs increase habitat heterogeneity and biodiversity at multiple scales across

2662-610: Is generally semi-arid and continental ( Köppen climate classification BSk ) and is drier and windier in comparison to most of the United States with greater temperature extremes. Much of this is due to the topography of the state. Summers in Wyoming are warm with July high temperatures averaging between 80 and 90 °F (27 and 32 °C) in most of the state. With increasing elevation, however, this average drops rapidly with locations above 9,000 feet (2,700 m) averaging around 70 °F (21 °C). Summer nights throughout

Residents of the state are known as Coloradans , although the antiquated "Coloradoan"

With Mexican independence in 1821, it was considered part of Alta California . U.S. expansion brought settlers who fought for control. Mexico ceded these territories after its defeat in 1848 in the Mexican–American War . From the late 18th century, French-Canadian trappers from Québec and Montréal regularly entered

3630-599: Is occasionally used. Major parts of the economy include government and defense, mining, agriculture , tourism, and increasingly other kinds of manufacturing. With increasing temperatures and decreasing water availability, Colorado's agriculture forestry, and tourism economies are expected to be heavily affected by climate change . The region that is today the State of Colorado has been inhabited by Native Americans and their Paleoamerican ancestors for at least 13,500 years and possibly more than 37,000 years. The eastern edge of

3751-510: Is partially protected from prevailing storms that blow in from the Pacific Ocean region by the high Rockies in the middle of Colorado. The "Front Range" includes Denver, Boulder , Fort Collins , Loveland, Castle Rock , Colorado Springs, Pueblo, Greeley, and other townships and municipalities in between. On the other side of the Rockies, the significant population centers in western Colorado (which

3872-604: Is practiced by ranching families throughout the grassland. The area includes both sagebrush and grassland plant communities, which interact with a range of ecological disturbances to support diverse wildlife species. Management for biodiversity in this complex ecosystem depends on managing for a shifting mosaic of different disturbances to meet the needs of multiple species. Researchers surveyed birds on active black-tailed prairie dog colonies and previously burned areas, as well as on paired undisturbed sites, and found that only prairie dog colonies supported breeding habitat for

This point, which is the highest low elevation point of any state,

4235-432: Is very prone to droughts. Most of the precipitation comes from thunderstorms, which can be severe, and from major snowstorms that occur in the winter and early spring. Otherwise, winters tend to be mostly dry and cold. In much of the region, March is the snowiest month. April and May are normally the rainiest months, while April is the wettest month overall. The Front Range cities closer to the mountains tend to be warmer in

4356-847: The American Civil War . While many gold seekers held sympathies for the Confederacy , the vast majority remained fiercely loyal to the Union cause. In 1862, a force of Texas cavalry invaded the Territory of New Mexico and captured Santa Fe on March 10. The object of this Western Campaign was to seize or disrupt Colorado and California's gold fields and seize Pacific Ocean ports for the Confederacy. A hastily organized force of Colorado volunteers force-marched from Denver City, Colorado Territory , to Glorieta Pass , New Mexico Territory, in an attempt to block

The later three ships were named in honor of the state, including an armored cruiser and the battleship USS Colorado , the latter of which was the lead ship of her class and served in World War II in the Pacific beginning in 1941. At the time of the attack on Pearl Harbor , the battleship USS Colorado was located at

Others were traveling overland west to the Oregon Country , the new goldfields of California , or the new Mormon settlements of the State of Deseret in the Salt Lake Valley , avoided the rugged Southern Rocky Mountains , and instead followed the North Platte River and Sweetwater River to South Pass (Wyoming) , the lowest crossing of the Continental Divide between

4840-544: The Compromise of 1850 divided the Mexican Cession and the northwestern claims of Texas into a new state and two new territories, the state of California , the Territory of New Mexico , and the Territory of Utah . On April 9, 1851, Hispano settlers from the area of Taos settled the village of San Luis , then in the New Mexico Territory , as Colorado's first permanent Euro-American settlement , further cementing

During it however the Columbine Mine massacre resulted in six dead strikers following a confrontation with Colorado Rangers . In a separate incident in Trinidad
