The park's resources include a deactivated intercontinental ballistic missile silo and a launch control facility where soldiers waited in an underground capsule for presidential instructions to launch Minuteman II missiles. The missiles were key to the U.S. military's defense systems during the Cold War.
After the Soviet Union fell and the arms reduction treaty was signed with Russia in 1991, the missile program was decreased dramatically.
The National Park Service is now planning for the site, a portion of which could open next summer.
