1956 Map of Sioux Pine Island

About this map

Sioux Pine Island sits at the heart of this Northwoods landscape, surrounded by the deep waters of the Boundary Waters Canoe Area Wilderness. This 1950s survey, updated with revisions in the early 1980s, details a complex network of glacial lakes and islands within the Superior National Forest. To the south, the waters of Kabetogama Lake and Vermilion Lake meet a shoreline defined by the Vermilion Lake State Forest. The map documents traditional travel routes through the dense timber, including the Canfield Portage connecting Canfield Portage Bay to the south. Notable landmarks for navigators and historians include Five Sisters Islands, Steamboat Island, and Trout Rock, which reflect the localized naming conventions of the region's early recreational and forestry era.
