The Geographic Center of the United States
On August 21, 2007, the Belle Fourche Chamber of Commerce and the Center of the Nation Planning Committee unveiled a new monument to designate and celebrate Belle Fourche, South Dakota as the Geographic Center of the United States.
The 21-foot diameter structure is made of etched South Dakota granite with a 12-inch bronze marker from the National Geodetic Survey. The Monument is located at the Belle Fourche Chamber and Visitor Information Center/Tri-State Museum buliding, 415 5th Avenue North. Additional phases to the project will occur in the near future. Plans include an avenue of flags, picnic area, educational kiosks and more.
