The story board, located across Wyatt Earp Boulevard from the Dodge City Santa Fe Depot, describes the importance of the 100th Meridian to the country's history and the location of the actual marker. The 100th Meridian, although an imaginary line on the surface of the earth, has long symbolized the end of the east and the beginning of the west. It figures prominently in many other designations and history of the area as this story board explains.
