About this map

Curtain Falls marks a prominent hydrological point on this borderland survey, where the waters of Crooked Lake spill toward the larger expanse of Iron Lake. The landscape is dominated by a complex network of interconnected waterways and islands, including the centrally located Three Island. This area, situated along the international boundary between Minnesota and Ontario, remains largely roadless, defined instead by its drainage patterns and glacial lake systems.

Water moves through the region via the Beartrap River and Stuart River, which feed into various smaller basins like Sunday Lake and White Feather Lake. The map reveals a wilderness character where the primary landmarks are named for their natural forms or proximity to larger bodies, such as Sterling Lake and the smaller Sterling Creek. For those studying the geography of the Boundary Waters and Quetico regions, this document provides a precise look at the shoreline configurations and water levels of the early 21st century.
