Denver's position near the mineral-rich Rocky Mountains encouraged mining and energy companies to spring up in the area. In the early days of the city, gold and silver booms and busts played a large role in the city's economic success. In the 1970s and early 1980s, the energy crisis in America and resulting high oil prices created an energy boom in Denver captured in the soap opera Dynasty. Denver was built up considerably during this time with the construction of many new downtown skyscrapers. When the price of oil dropped from $34 a barrel in 1981 to $9 a barrel in 1986, the Denver economy also dropped, leaving almost 15,000 oil industry workers in the area unemployed (including former mayor and current governor John Hickenlooper, a former geologist), and the nation's highest office vacancy rate (30%). The industry has recovered and the region has 700 employed petroleum engineers. Advances in hydraulic fracturing have made the DJ Basin of Colorado into an accessible and lucrative oil play. Energy and mining are still important in Denver's economy today, with companies such as EnCana, Halliburton, Smith International, Rio Tinto Group, Newmont Mining, Noble Energy, and Anadarko headquartered or having significant operations. Denver is in 149th place in terms of the cost of doing business in the United States.

Denver used to be a major trading center for beef and livestock when ranchers would drive (or later transport) cattle to the Denver Union Stockyards for sale. As a celebration of that history, for more than a century Denver has hosted the annual National Western Stock Show, attracting as many as 10,000 animals and 700,000 attendees. The show is held every January at the National Western Complex northeast of downtown.
Denver has many nationally recognized museums, including a new wing for the Denver Art Museum by world-renowned architect Daniel Libeskind, the second largest Performing Arts Center in the nation after Lincoln Center in New York City and bustling neighborhoods such as LoDo, filled with art galleries, restaurants, bars and clubs. That is part of the reason why Denver was, in 2006, recognized for the third year in a row as the best city for singles. Denver's neighborhoods also continue their influx of diverse people and businesses while the city's cultural institutions grow and prosper. The city acquired the estate of abstract expressionist painter Clyfford Still in 2004 and built a museum to exhibit his works near the Denver Art Museum. The Denver Museum of Nature and Science holds an aquamarine specimen valued at over $1 million, as well as specimens of the state mineral, rhodochrosite. Every September the Denver Mart, at 451 E. 58th Avenue, hosts a gem and mineral show. The state history museum, History Colorado Center, opened in April 2012. It features hands-on and interactive exhibits, artifacts and programs about Colorado history. It was named in 2013 by True West Magazine as one of the top-ten "must see" history museums in the country. History Colorado's Byers-Evans House Museum and the Molly Brown House are nearby.
