2022 Map of Oak Island

About this map

Apostle Islands National Lakeshore preserves a distinctive archipelago within the cold waters of Lake Superior, where land and water meet along the border of Ashland and Bayfield counties. The central feature is Oak Island, marked by its significant elevation and a network of footpaths including the Oak Island Trl. To the east, the map reveals the western portions of Manitou Island and Stockton Island, the latter featuring the prominent Quarry Point along its southwestern shore. This survey details the bathymetry and navigational hazards of the West Channel, identifying the submerged Oak Island Shoal and the steep coastal features of the Clay Banks. The isolation of Hermit Island and Otter Island highlights the remote nature of these islands, which are largely defined by their rugged topography and lack of modern road infrastructure, relying instead on established trails like the Otter Island Trl and Manitou Island Trl.
