The Mile High City nickname may come up a little short when describing Denver. The U-S Geodetic Survey's newest calculations show some parts of the city, including the state capitol, are 3 feet higher than 5,280 feet. But geologists stressed that doesn't mean Denver needs to change its famous nickname, and the mayor's office said there are no plans to do so. Mayor Wellington Webb's spokesman Andrew Hudson said the city's nickname won't change. Reflecting cartographic accuracy more than geologic uplifting, the new calculations set the official heights of many Colorado landmarks and the central Rockies as much as 7 feet higher than previously thought. The changes weren't big enough to shake up the rankings of anyof the state's 54 14,000-foot peaks, or create any new 14ers.
