2011 Map of Beaver Island South OE W

About this map

Lake Michigan surrounds this portion of the archipelago in Charlevoix County, defining a landscape dominated by the open waters of northern Lake Michigan. The eastern edge of the map identifies the western shoreline of Beaver Island, where the land meets the lake. Further offshore to the west, the underwater topography is marked by Richards Reef, a notable navigational feature in these northern waters. This 2011 survey by the U.S. Geological Survey focuses on the aquatic environment and the precise coastal boundary of the island, documenting the geographic relationship between the landmass and the surrounding lake floor features.
