1956 Map of Minnesota Ridge

About this map

Minnesota Ridge dominates the central topography of this mid-century survey, a high-relief landscape within the Black Hills National Forest along the Lawrence and Pennington county line. The settlement of Rochford anchors the southwestern corner at the junction of the South Fork Rapid Creek and the North Fork Rapid Creek, where two major rail lines, the Chicago and North Western and the Burlington and Quincy, converge. This junction reflects a legacy of industrial transport through the hills, supporting local extractive efforts like the Montana Mine (Inactive) further north.
