Colorado for the red colored (Spanish: colorado) silt the river carried from the mountains. On August 1, 1876, U.S. President Ulysses S. Grant signed a proclamation admitting Colorado as the 38th state. Colorado is nicknamed the "Centennial State" because it was admitted to the Union in 1876, the centennial year of the United States Declaration of Independence.

Colorado is bordered by the northwest state of Wyoming to the north, the midwest states ofNebraska and Kansas to the northeast and east, on the south by New Mexico and a small portion of the southern state of Oklahoma, 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, which is known as the heart of the American Southwest. 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, 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 used.[7][8]
