Tornadoes are rare west of the I-25 corridor; however, one notable exception was an F3 tornado that struck 4.4 miles south of downtown on June 15, 1988. On the other hand, the suburbs east of Denver and the city's east-northeastern extension (Denver International Airport) can see a few tornadoes, often weak landspout tornadoes, each spring and summer—especially during June with the enhancement of the Denver Convergence Vorticity Zone (DCVZ). The DCVZ, also known as the Denver Cyclone, is a variable vortex of storm-forming air flow usually found north and east of downtown, and which often includes the airport. Heavy weather from the DCVZ can disrupt airport operations. In a study looking at hail events in areas with a population of at least 50,000, Denver was found to be ranked 10th most prone to hail storms in the continental United States. In fact, Denver has received three of the top 10 costliest hailstorms in United States history, which occurred on July 11, 1990; July 20, 2009; and May 8, 2017 respectively.
Hollman is proud to have produced lockers integrated into the new scrupulously designed Apple Campus in Cupertino, CA. Coined as the “One Last Thing” Steve Jobs had envisioned prior to his death in 2011, the campus includes a 100,000 square foot Wellness Center with a two-story yoga room dotted with trees, plus an air-conditioning system that sucks outdoor air in to remind employees of the environment outside. In that beautifully designed environment, our Hollman Lockers gleam as brilliantly white as a 2001 iPod. Read the full story
In the closing years of the 19th century Don Melchor de Concha y Toro discovered that his most treasured wines had been pilfered from the “casillero” (cellar) beneath his family home. To discourage further theft, the enterprising Don spread a rumor that his deepest, darkest cellars were haunted by the devil. Today, the original Concha y Toro family estate, complete with its Devil’s Cellar, is Chile’s leading tourist destination!
From 1953 to 1989, the Rocky Flats Plant, a DOE nuclear weapon facility that was about 15 miles from Denver, produced fissile plutonium "pits" for nuclear warheads. A major fire at the facility in 1957, as well as leakage from nuclear waste stored at the site between 1958 and 1968, resulted in the contamination of some parts of Denver, to varying degrees, with plutonium-239, a harmful radioactive substance with a half-life of 24,200 years. A study by the Jefferson County health director, Dr. Carl Johnson, in 1981, linked the contamination to an increase in birth defects and cancer incidence in central Denver and nearer Rocky Flats. Later studies confirmed many of his findings. Plutonium contamination was still present outside the former plant site as of August 2010, and presents risks to building the envisioned Jefferson Parkway, which would complete Denver's automotive beltway.
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.
