A rancher and developer is donating 1.4 acres near the former Rocky Flats plant for the Rocky Flats Cold War Museum.
Museum board member Charles Church McKay recently donated the land, which is located between Golden and Boulder east of Colorado 93.
McKay is the nephew of Marcus Church, whose land was purchased by the federal government in 1951 under threat of condemnation for the nuclear weapons plant.
Board president Kim Grant says the donation was made on the condition that the museum be financed and ready for groundbreaking by January First, 2008.
Cleanup of the site finished late last year and the government plans a wildlife refuge there.
The museum is to document the historical, social, environmental and scientific aspects of the Rocky Flats Nuclear Weapons Plant and the Cold War.
