Denver, the capital of the American state of Colorado, has the nickname the Mile High City
Because, at one of its points, it measures 5,280 feet (1,609 m) in height. This measurement is exactly one mile above sea level. A round brass piece embedded in one of the steps of the Colorado State Capitol building's Western entrance marks the exact spot in which Denver's altitude is precisely one mile high.
Unlike most American cities that were centered close to a railroad, seaport or other hub of transportation, Denver was an early gold center. Denver was founded in 1858 during the Pikes Peak Gold Rush and incorporated in 1861. Being so far up from sea level, Denver offers beautiful views of the Rocky Mountains. Although Denver is Colorado's largest city, many people also appreciate the outdoor activities its natural beauty offers.
As many travelers aren't used to such elevated altitudes as the Mile High City has, it may take some people a few days to adjust. For some, no adjustment is needed while others get altitude sickness. Altitude sickness often includes headaches and a queasy stomach. Drinking a lot of water can help ease the symptoms. Drinking enough water is also necessary in Denver as well as most of Colorado, as the climate tends to be dry.
