This late nineteenth-century atlas map by Rand, McNally & Co. details the Upper Peninsula of Michigan and the entirety of Lake Superior, extending north to Ontario, Canada, and south to the northern tip of Michigan's Lower Peninsula. The map meticulously records the township and range survey grid across the Upper Peninsula, delineating counties such as Ontonagon, Baraga, Marquette, Schoolcraft, Delta, Menominee, and Mackinac. The map highlights the booming industrial and mining landscape of the region following the post-Civil War resource rush, charting the Copper Country of the Keweenaw Peninsula alongside the iron ranges of Marquette and Menominee. Rail lines, mining settlements, lighthouses, harbor points, and navigational waterways are comprehensively indexed, reflecting the vital shipping networks connecting the Great Lakes to Midwestern industrial centers.
