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.

Map of Grand Marais Harbor dated September 1883 shows breakwater, dredged area and soundings reduced to low water. The harbor's western point is named Howenstine's Point and the eastern point is named Mayhew's Point both after Grand Marais settlers. Structures, post office, docks, fish house and stables are identified along the harbor.
