Colorado, which has an average elevation of 6,800 feet (2,073 m), has the highest average altitude.
Alaska’s average elevation is just 1,900 feet (579 m).
This is because many parts of Alaska lie at or near sea level.
But the lowest spot in Colorado is still 3,350 feet (1,021 m) above sea level, near the town of Holly on the Arkansas River.
The highest peak in Colorado is Mount Elbert, one of many high mountains in the Sawatch range of the Rocky Mountains.
It rises 14,433 feet (4,402 m), or 2.73 miles (4.4 km), above sea level.
Colorado has 53 mountains that reach more than 14,000 feet (4,267 m) above sea level, and 831 that rise between 11,000 feet (3,353 m) and 14,000 feet (4,267 m).
