DENVER - For four years, thousands of drivers passed the cloud sculptures on Pena Boulevard outside Denver International Airport each day.
But it turns out the clouds had a secret inside -- bees!
A colony of bees had moved in, built a hive and were busy making honey.
There were so many bees that the hive contained nearly 20 pounds of honey.
The beehive was found when crews took the cloud sculptures to a refurbishing shop as part of its move to the Children's Museum. But by the time it got to the shop, the bees were gone. We're told workers took some of the honey home, but some of the beehive is being left inside the cloud as a secret only a few people know about.
The clouds, officially called Cloudscape, were installed next to southbound Pena in 2010. At the time, officials said the sculptures would likely stay a year or so. They stayed for four years.
Now the sculptures have been moved to a fabrication shop. They're being refurbished before they move to the Children's Museum of Denver next year. Officials said the clouds will be placed in area where they can be seen by drivers on Interstate 25.
The three sculptures range in size from 15 to 40 feet and are "comprised of clouds perched atop steel towers reminiscent of the oil well towers, water pump, and utility towers scattered across Colorado," officials said.
The artwork was made by former Colorado resident artist Christopher Lavery. Lavery said he took his inspiration for the sculpture from Colorado's vivid sky and sunsets.
"They catch the sun and translate light through them," said Chasansky. "It's a piece about the plains and the ingenuity and the vision of the plains that you get from what people have constructed."
There's no word yet on what's inside DIA's other infamous artwork -- the Big Blue Horse, aka Blucifer.
