At the foothills of the Rocky Mountains, what "Mile High City" lies 5,280 feet above sea level?
Answer Denver
Want to stand exactly a mile high in the Mile High City? Climb no further than the 13th step (or the 15th, depending on who you ask) of Denver's state capitol building. A demarcation upon this step dictates that it's exactly 5,280 feet above sea level. So, get your walking shoes...but beware of altitude sickness.
