About this map

Trout Lake dominates this mid-century survey of the Boundary Waters region, where massive landmasses like Pine Island and Sioux Pine Island create a complex network of bays and channels. The landscape is defined by its transition from the Superior National Forest in the north to the Minnesota State Forest further south, illustrating the coordinated conservation efforts between state and federal agencies in St. Louis County.

Evidence of historical water-based travel is preserved through named landmarks like Canfield Portage and Portage Bay. Smaller islands, including the Five Sisters Islands, Steamboat Island, and St Marys Island, dot the larger bodies of water, while the presence of the Breitung township boundary and the National Forest Boundary reflects the formal partitioning of this wilderness for management and resource rehabilitation by the Iron Range Resources and Rehabilitation Commission.
