Why is Denver Called the Mile High City?
Denver, Colorado, proudly carries the nickname “Mile High City” because its official elevation is exactly one mile (5,280 feet or 1,609 meters) above sea level. This specific elevation is measured at the 15th step of the State Capitol building, making it a popular spot for tourists to take photos and experience the altitude.
The History of Denver’s Elevation Measurement
The story of how Denver earned its moniker is tied to the construction of the Colorado State Capitol building. Completed in 1894, the building’s design incorporated the precise measurement of Denver’s elevation. Initial surveys placed the city’s altitude slightly below a mile high. However, later measurements, and specifically the installation of a marker on the 15th step of the west side of the Capitol, cemented the city’s claim.
There’s been some playful debate over the years regarding the exactness of the “mile high” designation. Discrepancies arose with advancements in surveying technology. To address this, a more accurate marker was installed in 2003, confirming Denver’s elevation at 5,280 feet. Wikipedia provides detailed information about Denver’s history and its unique geographic location.
What Does Being a Mile High Mean?
Living or visiting a city at this altitude can have physiological effects. The air is thinner due to lower atmospheric pressure, meaning there’s less oxygen available. This can lead to altitude sickness, especially for those not accustomed to it. Symptoms may include headache, fatigue, nausea, and shortness of breath.
However, the thinner air also contributes to Denver’s bright sunshine and clear blue skies. The reduced amount of atmosphere filters less sunlight, resulting in increased UV radiation. This also impacts athletic performance, as athletes need to adjust to the reduced oxygen levels for optimal endurance. For tourists, it’s commonly recommended to stay hydrated, avoid strenuous activity upon arrival, and limit alcohol consumption to acclimate to the altitude.
Denver’s Mile High Identity
The “Mile High City” nickname is deeply ingrained in Denver’s culture. The Denver Broncos, the city’s NFL team, play in Empower Field at Mile High. Various businesses and organizations use “Mile High” in their names, further solidifying the city’s unique identity. This celebrated elevation is a point of pride and a significant part of Denver’s appeal, attracting visitors who want to experience the challenge and beauty of a city perched a mile above sea level.
