Total magnetic intensity anomaly (relative to the earth's magnetic field), color coded, scale 1:250,000. Interpretation of magnetic data collected from airborne surveys, the map colors indicate the distribution and concentration of magnetic minerals (primarily iron-bearing) within the upper crust of the earth.

This atlas accompanies the International Joint Commission's report concerning the Rainy Lake waterway between the United States and Canada. The Commission's efforts were concentrated on the traditional voyageurs highway, which now divides the Boundary Waters Canoe Wilderness Area and Quetico Provincial Park.
