About this map

The international border between the United States and Canada bisects this wilderness landscape, separating the Quetico Provincial Park in Ontario from the Superior National Forest in Minnesota. The map documents a complex aquatic geography defined by interconnected waterways such as Carp Lake, Knife Lake, and Ensign Lake. In the early 1980s, this area remained largely inaccessible by road, characterized instead by a dense network of portages connecting isolated bodies of water like Trident Lake and Vera Lake.

Landmarks like Isles of Pine and Robbins Island dot the larger lakes, while the Boundary Waters Canoe Area Wilderness designation highlights the region's protected status. The presence of numerous named rapids and the Knife River illustrates the natural flow of the watershed through the Rainy River District and Lake County boundary, emphasizing the region's historical importance as a transit corridor for canoe travel.
