Colorado

Colorado (, other variants) is a state in the Mountain West subregion of the Western United States. It includes most of the Southern Rocky Mountains as well as the northeastern part of the Colorado Plateau, and the western edge the Great Plains. Colorado is the eighth most extensive and 21st most populous U.S. state. The 2020 United States Census estimated that Colorado’s population was 5,773,714, a 14.80% increase over the 2010 Census.

Native Americans have lived in the region for more than 13,000 year. The Lindenmeier site contains artifacts that date back to approximately 9200 to 1000 BC. The eastern edge of Rocky Mountains was an important migration route for early Americans who spread throughout the Americas. “Colorado” is the Spanish adjective meaning “ruddy”, the color of red sandstone. The Territory of Colorado was organized on February 28, 1861, and on August 1, 1876, U.S. President Ulysses S. Grant signed Proclamation 230 admitting Colorado to the Union as the 38th state. Colorado is nicknamed the “Centennial State” because it became a state one century after the signing of the United States Declaration of Independence.

Colorado is bordered by Wyoming to the north, Nebraska to the northeast, Kansas to the east, Oklahoma to the southeast, New Mexico to the south, and Utah to the west, as well as touching Arizona to the southwest at the Four Corners. Colorado is noted for its vivid landscape of mountains, forests, high plains, mesas, canyons, plateaus, rivers, and desert lands. Colorado is one of the Mountain States, and is a part of the western and southwestern United States.
