About this map

Superior National Forest defines this borderland landscape, where the international boundary between Canada and the United States threads through a dense network of glacial lakes and waterways. Iron Lake sits at the heart of this aquatic system, linked to the expansive Lac la Croix and the churning waters of Curtain Falls. The geography is shaped by the flow of the Beartrap River and Stuart River, which connect smaller interior basins like Sunday Lake, Sundial Lake, and White Feather Lake.

This 2019 survey reflects a wilderness area managed for conservation, largely devoid of modern road infrastructure. The map details the complex shoreline of Crooked Lake and distinctive landforms like Three Island, providing a precise record of the hydrologic connections and forest boundaries in Saint Louis County. It is a vital document for understanding the contemporary state of this protected ecosystem along the Ontario-Minnesota border.
