1981 Map of Lake Insula

About this map

Disappointment Mountain and the sprawling waters of the Boundary Waters Canoe Area Wilderness anchor this northern Minnesota landscape. In the early 1980s, the terrain was defined by an intricate network of glacial lakes and portages, including Disappointment Lake and the expansive Lake Insula. The map shows a region almost entirely devoid of permanent structures, instead highlighting the primitive travel routes that shaped human interaction with the wilderness. The Kawishiwi River flows through the central portion of the sheet, connecting major water bodies like Hudson Lake. Notable land features such as Williamson Island and The Rock provide specific navigational points for those traversing the Superior National Forest. Historic paths like the Snowbank Trail and Old Pines Trail represent the terrestrial links between these diverse aquatic systems, including smaller named basins such as Museum Lake and Starlight Lake.
