1902 Map of Edgemont

About this map

Edgemont serves as the central hub of this South Dakota landscape, situated at the confluence of the Cheyenne River and several major drainage systems. Surveyed at the turn of the century, the map reveals a rugged western environment where the Burlington and Missouri River R. R. dictates the pattern of settlement, linking small communities like Marietta, Rumford, and Ardmore. The northeastern corner is dominated by the Harney National Forest and complex canyon systems such as Red Canyon and Hell Canyon. Of particular historical interest is the presence of the Fossil Cycad National Monument, marking a specific era of paleontological preservation. The map also captures early industrial activity through a labeled Quarry and various settlements like Cascade Springs and Minnekahta that were vital to the regional economy before later twentieth-century changes altered the local geography.
