History of Colorado
History of the U.S. State of Colorado
The region that is today the U.S. State of Colorado has been inhabited by Native Americans and their Paleo-American ancestors for at least 13,500 years, and possibly more than 37,000 years. The eastern edge of the Rocky Mountains was a major migration route that was important to the spread of early peoples throughout the Americas. The Lindenmeier site in Larimer County contains artifacts dating from approximately 8720 BCE. When explorers, early trappers, hunters, and gold miners visited and settled in Colorado, the state was populated by American Indian nations.
