1963 Map of Michigan Island

USGS Topo · Published 1965

About this map

Michigan Island and the surrounding waters of Lake Superior dominate this 1963 hydrographic and topographic study within La Pointe Twp. The map provides a specialized look at the maritime geography of the eastern Apostle Islands, emphasizing coastal navigation and underwater terrain. Key navigational markers are documented, including the Michigan Island Light on the southwestern tip of its namesake island and the Gull Island Light positioned to the northeast. Beyond the prominent landmasses, the survey details significant hazards and features like Gull Island Shoal and the southern edge of Outer Island at Sand Point. This record is particularly valuable for its bathymetric data, showing the varying depths of the lake floor as it transitions from the shallow shoals to the deeper waters of the open lake during the mid-twentieth century.
