1902 Map of Edgemont

About this map

The Cheyenne River carves a winding path through the southwest corner of South Dakota, serving as the primary geographic axis for this 1902 survey. Edgemont emerges as the regional hub at the junction of several rail lines, where the Burlington and Missouri River R. R. follows the river valley and pushes south toward the Nebraska border. The landscape is defined by a dense network of drainages and named canyons, such as Red Canyon and Coal Canyon, that hint at the geological explorations of the era.
