"Colorado es un estado al oeste de los Estados Unidos de América. Es conocido por tener los picos más altos de las Montañas Rocosas, que dominan la parte occidental del estado, ya que la oriental consiste en grandes llanuras. La capital del estado, así como la ciudad más grande, es Denver, cuya área metropolitana concentra más de la mitad de la población del estado (2,3 millones de habitantes, de un total de 4,3 millones). El estado fue llamado así por el río Colorado, el nombre que los colonizadores españoles le dieron al río.El 1 de agosto de 1876 el presidente Ulysses S. Grant firmó una proclamación admitiendo a Colorado como el estado 38 de Estados Unidos, es el apodado «estado Centenario», ya que fue admitido a la Unión en 1876 el año del centenario de la Declaración de Independencia de Estados Unidos. La Oficina Postal de los Estados Unidos utiliza CO como abreviatura de este estado. Varios buques llamados USS Colorado recibieron este nombre en honor a Colorado."
"Colorado (/klrædo/, or /klrdo/) (Spanish for "ruddy") is a state in the United States encompassing 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 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 5,456,574 on July 1, 2015, an increase of 8.50% since the 2010 United States Census. The state was named for the Colorado River, which Spanish travelers 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 Proclamation 230 admitting Colorado to the Union as the 38th state. Colorado is nicknamed the "Centennial State" because it became a state in the same year as the centennial 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, Utah to the west, and 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. Denver is the capital and the most populous city of Colorado. Residents of the state are properly known as "Coloradans", although the term "Coloradoan" has been used archaically and lives on in the title of Fort Collins' newspaper, the Coloradoan."
