1955 Map of Diorite

USGS Topo · Published 1992

About this map

Mining operations and iron-ore transportation dominate this mid-century landscape in the Upper Peninsula. The small settlement of Diorite serves as a focal point along the Chicago and North Western rail line, which provided the essential link between the inland mines and the Great Lakes ports. The map reveals a high concentration of mineral extraction sites concentrated in the southern half, ranging from the Michigan Gold Mine and American Mine to the Barnes and Hecker Mine Abandoned.
