1967 Map of Kempton Bay

About this map

Voyageurs National Park defines this aquatic landscape along the international border, where the vast waters of Rainy Lake meet the intricate shoreline of northern Minnesota. The map documents a complex network of islands and interconnected waterways, including the large Big Island and smaller landmarks like Emerald Island and Junior Island. The boundary between Ontario and Minnesota cuts diagonally across the open water, passing Manitou Rock and Anchor Island as it follows the historical navigation route. Inland, the terrain is pocketed with smaller water bodies such as Shoepack Lake, Oslo Lake, and Cruiser Lake, separated by a system of portages. This 1967 survey, updated with 1980s data, illustrates the transition from the deep waters of Kempton Bay and Moose Bay to the marshy, lake-strewn interior typical of the Canadian Shield.
