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.

Total magnetic intensity anomaly, contour, scale 1:250,000. Interpretation of magnetic data collected from airborne surveys, the map contours (lines of equal magnetic intensity) indicate the distribution and concentration of magnetic minerals (primarily iron-bearing) within the upper crust of the earth.

Image of a group of men standing outside of the Agate Bay House. Painted sign underneath the decorative peak on the covered porch. This was utilized as a boarding house for railroad workers. Also pictured is an intersection of a wooden sidewalk, one of the first built in Two Harbors, Minnesota. Managers are Brown, Butler, and Blake standing on the right side of the covered porch.
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.
Image of new steel bridge over Beaver River near Beaver Bay, Minnesota. Completed during the Trunk Highway 1 project, now known as Scenic Highway 61. A second, older bridge appears beneath the new bridge. Grand opening of the highway was celebrated in 1925, construction north of Two Harbors began 1922.
