Colorado is notable for its diverse geography, ranging from alpine mountains, arid plains and deserts with huge sand dunes, deep canyons, sandstone and granite rock formations, rivers, lakes, and lush forests.
The summit of Mount Elbert at 14,440 feet (4,401.2 m) elevation in Lake County is the highest point in Colorado and the Rocky Mountains of North America. Colorado is the only U.S. state that lies entirely above 1,000 meters elevation. The point where the Arikaree River flows out of Yuma County, Colorado, and into Cheyenne County, Kansas, is the lowest point in Colorado at 3,317 feet (1,011 m) elevation. This point, which holds the distinction of being the highest low elevation point of any state, is higher than the high elevation points of 18 states and the District of Columbia.
A little less than one half of the area of Colorado is flat and rolling land. Corn, wheat, hay, soybeans, and oats are all typical crops, and most of the villages and towns in this region boast both a water tower and a grain elevator. Irrigation water is available from the South Platte, the Arkansas River, and a few other streams, and also from subterranean sources, including artesian wells. As well as crop agriculture, eastern Colorado hosts considerable livestock, such as cattle ranches and hog farms.
Roughly 70% of Colorado's population resides along the eastern edge of the Rocky Mountains in the Front Range Urban Corridor between Cheyenne, Wyoming, and Pueblo, Colorado. This region 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, 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 is not considered the "Front Range") are the cities of Grand Junction, Durango, and Montrose.
The Continental Divide of the Americas extends along the crest of the Rocky Mountains. The area of Colorado to the west of the Continental Divide is called the Western Slope of Colorado. Drainage water west of the Continental Divide flows to the southwest via the Colorado River and the Green River into the Gulf of California.
Within the interior of the Rocky Mountains are several large parks which are high broad basins.
In southmost Colorado is the large San Luis Valley, where the headwaters of the Rio Grande are located.
To the west of the Great Plains of Colorado rises the eastern slope of the Rocky Mountains. Notable peaks of the Rocky Mountains include Longs Peak, Mount Evans, Pikes Peak, and the Spanish Peaks near Walsenburg, in southern Colorado. This area drains to the east and the southeast, ultimately either via the Mississippi River or the Rio Grande into the Gulf of Mexico.
The Rocky Mountains within Colorado contain about 53 peaks that are 14,000 feet (4,267 m) or higher in elevation above sea level, known as fourteeners. These mountains are largely covered with trees such as conifers and aspens up to the tree line, at an elevation of about 12,000 feet (3,700 m) in southern Colorado to about 10,500 feet (3,200 m) in northern Colorado. Above this only alpine vegetation grows. Only small parts of the Colorado Rockies are snow-covered year round.
Much of the alpine snow melts by mid-August with the exception of a few snowcapped peaks and a few small glaciers. The Colorado Mineral Belt, stretching from the San Juan Mountains in the southwest to Boulder and Central City on the front range, contains most of the historic gold- and silver-mining districts of Colorado. Mount Elbert is the highest summit of the Rocky Mountains. The 30 highest major summits of the Rocky Mountains of North America all lie within the state.
Colorado Western Slope
The Western Slope of Colorado is drained by the Colorado River and its tributaries (primarily the Gunnison River, Green River and the San Juan River) or by evaporation in its arid areas.
The city of Grand Junction, Colorado is the largest city on the Western Slope.
The Western Slope lies in close proximity to multiple notable destinations in the Colorado Rocky Mountains, including Glenwood Springs, with its resort hot springs, and the ski resorts of Aspen, Breckenridge, Vail, Crested Butte, Steamboat Springs, and Telluride.
The northwestern corner of Colorado is a sparsely populated region, and it contains part of the noted Dinosaur National Monument, which is not only a paleontological area, but is also a scenic area of rocky hills, canyons, arid desert, and streambeds. Here, the Green River briefly crosses over into Colorado.
From west to east, the land of Colorado consists of desert lands, desert plateaus, alpine mountains, National Forests, relatively flat grasslands, scattered forests, buttes, and canyons in the western edge of the Great Plains. The famous Pikes Peak is located just west of Colorado Springs. Its isolated peak is visible from nearly the Kansas border on clear days, and also far to the north and the south.
Desert lands in Colorado are located in and around areas such as the Pueblo, Canon City, Florence, Great Sand Dunes National Park and Preserve, San Luis Valley, Cortez, Canyon of the Ancients National Monument, Hovenweep National Monument, Ute Mountain, Delta, Grand Junction, Colorado National Monument, and other areas surrounding the Uncompahgre Plateau and Uncompahgre National Forest.
Colorado is one of four states in the United States that share a common geographic point - the Four Corners together with Arizona, New Mexico, and Utah. At this intersection, it is possible to stand in four states at once.
The climate of Colorado is more complex than states outside of the Mountain States region. Unlike most other states, southern Colorado is not always warmer than northern Colorado. Most of Colorado is made up of mountains, foothills, high plains, and desert lands. Mountains and surrounding valleys greatly affect local climate.
Northeast, east, and southeast Colorado are mostly the high plains, while Northern Colorado is a mix of high plains, foothills, and mountains. Northwest and west Colorado are predominantly mountainous, with some desert lands mixed in. Southwest and southern Colorado are a complex mixture of desert and mountain areas.
The climate of the Eastern Plains is a semi-arid climate. The area is known for its abundant sunshine and cool, clear nights, which give this area a great average diurnal temperature range. The difference between the highs of the days and the lows of the nights can be considerable as warmth dissipates to space during clear nights, the heat radiation not being trapped by clouds.
The Front Range urban corridor, where most of the population of Colorado resides, lies in a pronounced precipitation shadow as a result of being on the lee side of the Rocky Mountains.
In summer, this area can have many days above 95 °F (35 °C) and often 100 °F (38 °C). On the plains, the winter lows usually range from 25 to −10 °F (−4 to −23 °C). About 75% of the precipitation falls within the growing season, from April to September, but this area 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.
Front range foothills
Just west of the plains and into the foothills, there are a wide variety of climate types. Locations merely a few miles apart can experience entirely different weather depending on the topography. Most valleys have a semi-arid climate, which transitions to an alpine climate at higher elevations. There are also pockets of subtropical highland and humid subtropical climates.
Extreme weather changes are common in Colorado, although the majority of 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 in the northwest part of the state. The Eastern Plains have had some of the biggest hail storms in North America.
The Eastern Plains are part of the extreme western portion of Tornado Alley; some damaging tornadoes in the Eastern Plains include the 1990 Limon F3 tornado and the 2008 Windsor EF3 tornado, which devastated the small town. The plains are also susceptible to occasional floods, which are caused both by thunderstorms and by the rapid melting of snow in the mountains during warm weather.
Much of Colorado is a very dry state averaging only 17 in (430 mm) of precipitation per year statewide and rarely experiences a time when some portion of the state is not in some degree of drought. The lack of precipitation contributes to the severity of wildfires in the state.
However, some of the mountainous regions of Colorado receive a huge amount of moisture from winter snowfalls. The spring melts of these snows often cause great waterflows in the Yampa River, the Colorado River, the Rio Grande, the Arkansas River, the North Platte River, and the South Platte River.
Water flowing out of the Colorado Rocky Mountains is a very significant source of water for the farms, towns, and cities of the southwest states of New Mexico, Arizona, Utah, and Nevada, as well as the Midwest, such as Nebraska and Kansas, and the southern states of Oklahoma and Texas. A significant amount of water is also diverted for use in California; occasionally (formerly naturally and consistently), the flow of water reaches northern Mexico.
The region that is today the state of Colorado has been inhabited by Native Americans for more than 13,000 years.
The U.S. acquired a territorial claim to the eastern Rocky Mountains with the Louisiana Purchase from France in 1803. This U.S. claim conflicted with the claim by Spain to the upper Arkansas River Basin as the exclusive trading zone of its colony of Santa Fé de Nuevo Méjico. In 1806, Zebulon Pike led a U.S. Army reconnaissance expedition into the disputed region. Colonel Pike and his men were arrested by Spanish cavalrymen in the San Luis Valley the following February, taken to Chihuahua, and expelled from Mexico the following July.
The U.S. relinquished its claim to all land south and west of the Arkansas River and south of 42nd parallel north and west of the 100th meridian west as part of its purchase of Florida from Spain with the Adams-Onís Treaty of 1819. Mexico eventually ratified the Adams-Onís Treaty in 1831. The Texian Revolt of 1835–36 fomented a dispute between the U.S. and Mexico which eventually erupted into the Mexican–American War in 1846. Mexico surrendered its northern territory to the U.S. with the Treaty of Guadalupe Hidalgo at the conclusion of the war in 1848.
Most American settlers traveling overland west to the Oregon Country, namely 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.
In 1854, Senator Stephen A. Douglas persuaded the U.S. Congress to divide the unorganized territory east of the Continental Divide into two new organized territories, the Territory of Kansas and the Territory of Nebraska, and an unorganized southern region known as the Indian territory.
The election of Abraham Lincoln for the President of the United States on November 6, 1860, led to the secession of nine southern slave states and the threat of civil war among the states. The Republican Party-dominated Congress and admitted the eastern portion of the Territory of Kansas into the Union as the free State of Kansas on January 29, 1861, leaving the western portion of the Kansas Territory, and its gold-mining areas, as unorganized territory.
In 1862, a force of Texas cavalry invaded the Territory of New Mexico and captured Santa Fe on March 10. On March 28, the Coloradans and local New Mexico volunteers stopped the Texans at the Battle of Glorieta Pass and the Texans abandoned Santa Fe and returned to San Antonio in defeat. The Confederacy made no further attempts to seize the Southwestern United States.
In the midst and aftermath of Civil War, many discouraged prospectors returned to their homes, but a few stayed and developed mines, mills, farms, ranches, roads, and towns in Colorado Territory.
The United States Congress passed an enabling act on March 3, 1875, specifying the requirements for the Territory of Colorado to become a state. On August 1, 1876 (28 days after the Centennial of the United States), U.S. President Ulysses S. Grant signed a proclamation admitting Colorado to the Union as the 38th state and earning it the moniker "Centennial State".
The discovery of a major silver lode near Leadville in 1878 triggered the Colorado Silver Boom.
Colorado women were granted the right to vote beginning on November 7, 1893, making Colorado the second state to grant universal suffrage and the first one by a popular vote (of Colorado men).
Tourism became a mainstay of the state economy, and high technology became an important economic engine.
Three warships of the U.S. Navy have been named the USS Colorado. The first USS Colorado was named for the Colorado River. The later two ships were named in honor of the state, including the battleship USS Colorado which served in World War II in the Pacific beginning in 1941. At the time of the Attack on Pearl Harbor, this USS Colorado was located at the naval base in San Diego, Calif. and because of that wasn't harmed in the attack.
The United States Census Bureau estimates that the population of Colorado was 5,758,736 as of 2019, a 14.51% increase since the 2010 United States Census. Colorado's most populous city and capital, is Denver. The Greater Denver Metropolitan Area, with an estimated 2017 population of 3,515,374, is considered the largest metropolitan area within the state and is found within the larger Front Range Urban Corridor, home to about five million.
Spanish is the second-most-spoken language in Colorado, after English. There is one Native Coloradan language still spoken in Colorado, Colorado River Numic (Ute).
Colorado's most common religion is Christianity, and its most common denomination is Catholicism. Colorado, and mostly the city of Colorado Springs, serves as the headquarters of many Christian groups, many of them Evangelical.
The state's economy broadened from its mid-19th century roots in mining when irrigated agriculture developed, and by the late 19th century, raising livestock had become important. Early industry was based on the extraction and processing of minerals and agricultural products. Current agricultural products are cattle, wheat, dairy products, corn, and hay.
In the second half of the 20th century, the industrial and service sectors have expanded greatly. The state's economy is diversified and is notable for its concentration of scientific research and high-technology industries. Other industries include food processing, transportation equipment, machinery, chemical products, minerals such as gold and molybdenum, and tourism. Denver is also an important financial center.
A number of film productions have shot on location in Colorado, especially prominent Westerns like True Grit, The Searchers and Butch Cassidy and the Sundance Kid. A number of historic military forts, railways with trains still operating, mining ghost towns have been utilized and transformed for historical accuracy in well known films.
Colorado is known for its Southwest and Rocky Mountain cuisine. Mexican restaurants are prominent throughout the state.
Boulder, Colorado was named America's Foodiest Town 2010 by Bon Appétit. Boulder, and Colorado in general, is home to a number of national food and beverage companies, top-tier restaurants and farmers' markets. Boulder, Colorado also has more Master Sommeliers per capita than any other city, including San Francisco and New York.
The Food & Wine Classic is held annually each June in Aspen, Colorado. Aspen also has a reputation as the culinary capital of the Rocky Mountain region.
Denver is known for steak, but now has a diverse culinary scene with many top-tier restaurants.
Wine and beer
Colorado wines include award-winning varietals that have attracted favorable notice from outside the state. With wines made from traditional Vitis vinifera grapes along with wines made from cherries, peaches, plums and honey, Colorado wines have won top national and international awards for their quality. Colorado's grape growing regions contain the highest elevation vineyards in the United States, with most viticulture in the state practiced between 4,000 and 7,000 feet (1,219 and 2,134 m) above sea level.
Colorado's primary mode of transportation (in terms of passengers) is its highway system. Smaller communities are only connected to this network via county roads.
Denver International Airport (DIA) is the fourth busiest domestic U.S. airport and thirteenth busiest world airport DIA handles by far the largest volume of commercial air traffic in Colorado, and is the busiest U.S. hub airport between Chicago and the Pacific coast, making Denver the most important airport for connecting passenger traffic in the western United States.
Colorado is home to 4 national parks, 8 national monuments, 2 national recreation areas, 2 national historic sites, 3 national historic trails, a national scenic trail, 11 national forests, 2 national grasslands, 42 national wilderness areas, 2 national conservation areas, 8 national wildlife refuges, 44 state parks, 307 state wildlife areas, and numerous other scenic, historic, and recreational areas.
Some examples of the National Park System in Colorado are:
- Bent's Old Fort National Historic Site
- Dinosaur National Monument
- Mesa Verde National Park and UNESCO World Heritage Site
