1981 Map of Quadga Lake

About this map

Boundary Waters Canoe Area Wilderness dominates this corner of the Superior National Forest, revealing a complex aquatic landscape in Lake County during the early 1980s. The hydrography, compiled from Minnesota Department of Natural Resources data, shows a dense network of glacial basins and drainage systems. The Isabella River winds through the central terrain, connected by historical overland routes including Portage Isabella and several unnamed portages that link Quadga Lake with surrounding waters like Superstition Lake and Myth Lake. While the northern portion is defined by protected wilderness, the southern edge shows limited infrastructure, notably the Tomahawk Road and Northwest Road. This survey documents the area before modern management changes, preserving the locations of remote features such as Rock of Ages Lake, Bog Lake, and the small winter trail segments used for seasonal access.
