2017 Map of Trout Island

About this map

Lake Michigan dominates this nautical landscape, illustrating the remote maritime environment within the Beaver Island archipelago during the early 21st century. The map focuses on Trout Island, a small landmass defined by its low-lying terrain and isolated position. To the west, the submerged hazards of Trout Island Shoal present a significant feature for understanding local navigation and the underwater topography of these northern waters. The sheet also delineates the aquatic boundary between Mackinac Co and Charlevoix Co, tracing a line across the open water north of the island. This survey reflects the modern hydrographic and topographic state of the region, providing a clear record of shoreline and bathymetric extents for these Great Lakes islands.
