Nuke site, repurposed as Rocky Flats NWR, opens to public—for now

ROCKY FLATS, Colo. (Reuters) - Less than two miles (3 km) from where triggers for thermonuclear weapons were once manufactured and against the backdrop of Colorado’s Rocky Mountains, a bull elk bugles as he defends his harem of cows from rival males.

“It’s rutting season and this is mating behavior,” said David Lucas of the U.S. Fish & Wildlife Service, and manager of Rocky Flats National Wildlife Refuge, 12 miles (19 km) northwest of Denver.
