What state has the highest overall average altitude?

Colorado has the highest overall average altitude of any U.S. state, with an average elevation of about 6,800 feet (2,073 meters) above sea level. This is largely due to the Rocky Mountains, which run through the state and contain many peaks exceeding 14,000 feet. The combination of mountainous terrain and elevated plateaus contributes to Colorado's standing as the highest state in terms of average altitude.
