This early state map of Michigan illustrates both the Upper and Lower Peninsulas during a transformative era following Michigan's admission to statehood in 1837. Engraved by the prominent Boston engraver George W. Boynton, the map depicts early county configurations, township grids, nascent rail lines, primary settlements, and coastal soundings along Lake Superior, Lake Michigan, Lake Huron, and Lake Erie. The Upper Peninsula is divided into expansive early territories including Ontonagon, Schoolcraft, Michilimackinac, and Chippewa, reflecting pre-mining boom administrative layouts. In the Lower Peninsula, southern counties show dense settlement and early towns such as Detroit, Ann Arbor, Lansing, Grand Rapids, and Kalamazoo, while northern counties display historical or proposed county names such as Wabaunsee, Kaykakee, and Wyandot. Surrounded by neatline degree scales measured from both Greenwich and Washington, the map stands as an important cartographic record of antebellum Midwest geography.
