About this map

Charity Island and its smaller neighbors rise out of the shallow depths of Saginaw Bay in this 1970 snapshot of Arenac County’s maritime landscape. The island, which is part of Whitney Twp, is the largest landmass in the bay and shows evidence of past human occupation with the presence of Ruins at its northern tip. South of the main island, the land transitions into Gull Island and Little Charity Island, the latter falling within the boundaries of Sims Twp.

The map provides detailed hydrographic data compiled from a 1970 U.S. Lake Survey chart, illustrating the complex underwater topography surrounding these remote outposts. This survey is particularly useful for understanding the isolation of these islands before modern environmental protections were fully established, documenting the exact contours of the limestone reefs that connect Little Charity Island to the mainland.
