While Denver may not be as recognized for historical musical prominence as some other American cities, it has an active pop, jazz, jam, folk, and classical music scene, which has nurtured several artists and genres to regional, national, and even international attention. Of particular note is Denver's importance in the folk scene of the 1960s and 1970s. Well-known folk artists such as Bob Dylan, Judy Collins and John Denver lived in Denver at various points during this time and performed at local clubs. Three members of the widely popular group Earth, Wind, and Fire are also from Denver. More recent Denver-based artists include Nathaniel Rateliff & the Night Sweats, The Lumineers, Air Dubai, The Fray, Flobots, Cephalic Carnage, Axe Murder Boyz, Deuce Mob, and Five Iron Frenzy.
Denver International Airport (IATA: DEN, ICAO: KDEN), commonly known as DIA, serves as the primary airport for a large region surrounding Denver. DIA is 18.6 miles (30 km) east-northeast of the Colorado State Capitol. DIA is the eighteenth busiest airport in the world and ranks sixth in the United States, with 58,266,515 passengers passing through it in 2016. It covers more than 53 square miles (137.3 km2), making it the largest airport by land area in the United States and larger than the island of Manhattan. Denver serves as a major hub for United Airlines, is the headquarters for Frontier Airlines, and is the fastest-growing focus city for Southwest Airlines.
10. Silverthorne Ice Castles: These castles are like Disney’s ‘Frozen’ in the real world. Local artist Brent Christensen makes thousands of tons of ice into sculptures every year using icicles and sprinklers. The water freezes over the icicles creating towers, spires, walls, tunnels and cascades. In sunlight, the towers glow turquoise. By night, the ice glows from a hundred little lights placed in the ice structures.
Finally linked to the rest of the nation by rail, Denver prospered as a service and supply center. The young city grew during these years, attracting millionaires with their mansions, as well as the poverty and crime of a rapidly growing city. Denver citizens were proud when the rich chose Denver and were thrilled when Horace Tabor, the Leadville mining millionaire, built an impressive business block at 16th and Larimer as well as the elegant Tabor Grand Opera House. Luxurious hotels, including the much-loved Brown Palace Hotel, soon followed, as well as splendid homes for millionaires like the Croke, Patterson, Campbell Mansion at 11th and Pennsylvania and the now-demolished Moffat Mansion at 8th and Grant. Intent on transforming Denver into one of the world's great cities, leaders wooed industry and enticed laborers to work in these factories. Soon, in addition to the elite and a large middle class, Denver had a growing population of German, Italian, and Chinese laborers, soon followed by African-Americans and Spanish-surnamed workers. Unprepared for this influx, the Silver Crash of 1893 unsettled political, social, and economic balances, laying the foundation for ethnic bigotry, such as the Red Scare and the rise of the Ku Klux Klan, as well as corruption and crime.
