UNDERSTAND ROCKY FLATS
For nearly four decades, Rocky Flats was part of the nation's nuclear weapons complex, manufacturing plutonium components for nuclear weapons just northwest of Denver.
The plant operated beside rapidly growing Colorado communities. Its history includes fires, releases, environmental contamination, a federal investigation, shutdown, cleanup—and questions that continue today.
