COLORADO
Introduction
Colorado is a state of the United States of America that encompasses most of the Southern Rocky Mountains as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is part of the Mountain States, the Western United States, and the Southwestern United States. The High Plains of eastern Colorado may be considered part of the Midwestern United States.
Colorado is nicknamed the "Centennial State" because it was admitted to the Union as the 38th state in 1876, the centennial year of the United States Declaration of Independence. Colorado is bordered on the north by Wyoming and Nebraska, on the east by Nebraska and Kansas, on the south by Oklahoma and New Mexico, and on the west by Utah. The four states of Colorado, New Mexico, Arizona, and Utah meet at one common point known as the Four Corners. Colorado is one of only three U.S. states with no natural borders, the others being neighboring Wyoming and Utah.
Colorado is noted for its vivid landscape of mountains, plains, mesas, and canyons. The 30 highest major summits of the Rocky Mountains of North America all lie within the state. Colorado is home to 4 national parks, 6 national monuments, 2 national recreation areas, 2 national historic sites, 3 national historic trails, 1 national scenic trail, 11 national forests, 2 national grasslands, 41 national wilderness areas, 2 national conservation areas, 8 national wildlife refuges, 44 state parks, 1 state forest, 323 state wildlife areas, and numerous other scenic, historic, and recreational attractions.
The United States Census Bureau estimates that the state population was 5,024,748 on July 1, 2009, an increase of 16.82% since the U.S. Census 2000. Denver is the capital and the most populous city of Colorado. Residents of the state are properly known as "Coloradans", although the archaic term "Coloradoan" is still used.
Geography
Colorado is one of only three states (the others are Wyoming and Utah) that have only lines of latitude and longitude for borders. It stretches exactly from 37°N to 41°N, and 102°W to 109°W. The Four Corners Monument at its southwestern-most point is at 37°N and 109°W.
East of the Front Range of the Rocky Mountains are the Colorado Eastern Plains, the section of the Great Plains within Colorado at elevations ranging from 3,500 to 7,000 feet (1,000 to 2,000 m). Kansas and Nebraska border Colorado to the east. The plains are sparsely settled with most population along the South Platte and the Arkansas rivers and the I-70 corridor. Rainfall is meager, averaging about 15 inches (380 mm) annually. There is some irrigated farming, but much of the land is used for dryland farming or ranching. Winter wheat is a typical crop and most small towns in the region boast both a water tower and a grain elevator.
The major cities and towns lie just east of the Front Range, in the I-25 corridor. The majority of the population of Colorado lives in this densely urbanized strip.
To the west lay the Front Range of the Rocky Mountains with notable peaks such as Longs Peak, Mount Evans, Pikes Peak, and the Spanish Peaks near Walsenburg in the south. This area drains to the east, is forested, and partially urbanized. With urbanization, utilization of the forest for timbering and grazing was retarded, which resulted in accumulation of fuel. During the drought of 2002 devastating forest fires swept this area.
To the west of the Front Range lies the Continental Divide. To the west of the Continental Divide is the Western Slope. Water west of the Continental Divide drains into the Pacific Ocean via the Colorado River.
Within the interior of the Rocky Mountains are several large parks or high broad basins. In the north, on the east side of the Continental Divide is North Park. North Park is drained by the North Platte River, which flows north into Wyoming. Just south but on the west side of the Continental Divide is Middle Park, drained by the Colorado River. South Park is the headwaters of the South Platte River. To the south lies the San Luis Valley, the headwaters of the Rio Grande, which drains into New Mexico. Across the Sangre de Cristo Range to the east of the San Luis Valley lies the Wet Mountain Valley. These basins, particularly the San Luis Valley, lie along the Rio Grande Rift, a major geological formation, and its branches.
The Rocky Mountains within Colorado contain 54 peaks that are 14,000 feet (4270 m) or higher, known as fourteeners. The mountains are timbered with conifers and aspen to the tree-line, at an elevation of about 12,000 feet (4,000 m) in southern Colorado to about 10,500 feet (3,200 m) in northern Colorado; above this only alpine vegetation grows. The Rockies are snow-covered only in the winter; most snow melts by mid-August with the exception of 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.
The Western Slope is generally drained by the Colorado River and its tributaries. Notable to the south are the San Juan Mountains, an extremely rugged mountain range, and to the west of the San Juans, the Colorado Plateau, a high desert bordering Southern Utah. Grand Junction is the largest city on the Western Slope. Grand Junction is served by Interstate Highway I-70. To the southeast of Grand Junction is Grand Mesa, a large flat-topped mountain. Further east are the ski resorts of Aspen, Vail, Crested Butte, and Steamboat Springs. The northwestern corner of Colorado bordering Northern Utah and Western Wyoming is mostly sparsely populated rangeland.
From west to east, the state consists of desert-like basins, turning into plateaus, then alpine mountains, and then the grasslands of the Great Plains. Mount Elbert is the highest peak in the Rocky Mountains within the continental United States. The famous Pikes Peak is just west of Colorado Springs. Its lone peak is visible from near the Kansas border on clear days.
History
The word "Colorado" was selected by Congress in 1861 as the name for the territory that is today a state. The name has its origins in the Spanish language, where it is directly translated as "colored," and is often taken to mean "reddish colored."
The territory that ultimately became Colorado was added to the United States by the 1803 Louisiana Purchase and the 1848 Mexican Cession. The Colorado Gold Rush of 1859 (see also Fifty-Niner) brought many settlers to the Denver area, though the population collapsed following an initial mining boom. The Colorado Territory was organized as a United States territory on February 28, 1861, and Colorado attained statehood August 1, 1876, (earning it the moniker the "Centennial State"). Colorado women were granted the right to vote starting on November 7, 1893.
Three different ships have been named USS Colorado in honor of this state.
