St Martins Bay and the northern reaches of Lake Huron define this 1932 advance sheet, which focuses on the maritime geography of Mackinac County. The map details the rugged shoreline and island chains south of the mainland, most notably the St Martins Islands and the solitary Isle St Martin. These landforms, along with the prominent Marquette Point, were documented during a transitional period in cartography, utilizing field examinations and aerial photographs taken by the Air Corps.
