About this map

Boundary Waters Canoe Area Wilderness and the Superior National Forest define this 1980s landscape of the Iron Range region. The area is characterized by an intricate network of waterways, centered on the expansive Gabbro Lake and Bald Eagle Lake. These lakes are connected by a series of portages and drainage systems including Bald Eagle Creek and Nickel Creek.

The presence of numerous Portage routes illustrates the importance of traditional canoe navigation across the glacial terrain. Distinctive landmarks such as Cobalt Pond and Bubbles Lake dot the dense forest, while the Isabella River and Snake River serve as primary arterial flows. This map reflects a period of careful management by the U.S. Forest Service, emphasizing the preservation of the wilderness boundary during the late twentieth century.
