Origin of Colorado State Name

Colorado come from the Spanish, "ruddy"or "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.

The name of the state, Colorado, has its origin in the Spanish language, as the word for "colored red". This was the name chosen for Colorado as a Territory in 1861 by Congress.

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.
