How The States Were Named
Have you ever wondered how our states were named? This article provides a general overview of the naming process.
Colorado is a Spanish adjective that means “red.” The early Spanish explorers in the Rocky Mountain region named a river they found the Rio Colorado for the reddish silt that the water carried down from the mountains. When Colorado became a territory in 1861, the Spanish word was used as a name because it was commonly thought that the Rio Colorado originated in the territory. This was not the case, however. Prior to 1921, the Colorado River began where the Green River of Utah and the Grand River of Colorado converged outside of Moab, Utah, and the United States Geological Survey identified Green River of Wyoming as the Colorado’s actual headwaters. The Rio Colorado did not actually flow through Colorado until 1921, when House Joint Resolution 460 of the 66th United States Congress changed the name of the Grand River. Learn more.
