2022 Map of Flag Island

About this map

Fort Saint Charles and the northernmost reaches of the United States define this map of the Northwest Angle, where the international boundary with Canada cuts across Lake of the Woods. This unique geographic anomaly features a complex archipelago of islands and inlets, including Magnusons Island, Penasse Island, and the historic settlement of Penasse near American Point. The map details the intricate waterways of Northwest Angle Inlet and Moose Bay, providing a clear view of the terrestrial and aquatic boundaries that have shaped local navigation and governance for generations. Smaller landforms like Honeymoon Island and Crowduck Island dot the lake, illustrating the dense concentration of islands that characterize this remote borderland.
