Rocky Flats Plant, Bounded by Indiana Street & Routes 93, 128 & 72, Golden, Jefferson County, CO

Significance: Established in 1951, it was a top-secret weapons production plant. The plant manufactured triggers for use in nuclear weapons and purified plutonium recovered from retired weapons (called site returns). Activities at the plant included production, stockpile, maintenance, and retirement and dismantlement. Particular emphasis was placed on production. Rocky Flats produced most of the plutonium triggers used in nuclear weapons from 1953-1964, and all of the triggers produced from 1964 until 1989, when production was suspended.
