About this map

Namakan Lake dominates this borderland survey, marking the watery boundary where the United States meets Canada at the Ontario and Minnesota line. The map highlights the complex archipelago and intricate shoreline of Voyageurs National Park, including the large mass of Namakan Island and the strategic Squaw Narrows. Evidence of early industrial and transit footprints appear through the Kettle Falls Dam and Squirrel Falls Dam at the northern edge of the sheet.

Resource extraction and land management are visible through the boundaries of the Kabetogama State Forest and Superior National Forest. While the interior is largely defined by water bodies like Net Lake and Wiyapka Lake, a lone Mine on Mica Island points to the area's geological history. The 1983 photorevisions capture the shoreline at a stable reservoir elevation of 1119 feet, documenting the landscape before further modern development.
