24545 Cottonwood Road · Philip, SD
This National Park Service site preserves pieces of a Minuteman II missile field that once held 150 missiles across southwestern South Dakota. It is spread over three stops along Interstate 90: a visitor center at exit 131, the Delta-01 launch control facility near exit 127 and the Delta-09 silo at exit 116. At Delta-09 you look down through a glass enclosure at an unarmed missile in its 80-foot launch tube. Going underground at Delta-01 requires a ranger tour reserved in advance.
