Which U.S. City Was The First To Host A National Park?

Did You Know!

One interesting fact about Denver, Colorado, is that it's known as the "Mile-High City" because its elevation is exactly one mile (5,280 feet or 1,609 meters) above sea level. There's even a specific spot on the steps of the Colorado State Capitol building that is marked as being precisely one mile high, making it a popular attraction for visitors. This high elevation affects everything from cooking times to athletic performance, as the thinner air has less oxygen and lower atmospheric pressure.
