Colorado State Flags

Colorado is part of the Western United States, the Southwestern United States, and the Mountain States. Colorado is the 8th most extensive and the 22nd most populous of the 50 United States. The United States Census Bureau estimates that the population of Colorado was 5,355,866 on July 1, 2014, an increase of 6.50% since the 2010 United States Census.

The state was named for the Colorado River, which Spanish travellers named the Río Colorado for the ruddy (Spanish: Colorado) silt the river carried from the mountains. The Territory of Colorado was organized on February 28, 1861, and on August 1, 1876, U.S. President Ulysses S. Grant signed a proclamation admitting Colorado to the Union as the 38th state. Colorado is nicknamed the "Centennial State" because it became a state 28 days after the centennial of the United States Declaration of Independence.

Colorado is bordered by the northwest state of Wyoming to the north, the Midwest states of Nebraska and Kansas to the northeast and east, on the south by New Mexico and Oklahoma, on the west by Utah, and Arizona to the southwest. The four states of Colorado, New Mexico, Utah, and Arizona meet at one common point known as the Four Corners, which is known as the heart of the American Southwest. Colorado is noted for its vivid landscape of mountains, forests, high plains, mesas, canyons, plateaus, rivers, and desert lands.

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 in use. Wikipedia
