About this map

Mining operations dominate the northern landscape of the Mesabi Range in this mid-century survey, where the heavy industry of the Patrick Mine, Harrison Mine, and Hawkins Mine defines the terrain. Extensive tailings ponds and mine dumps surround the industrial hubs of Cooley and the Cooley Post Office, showing the massive scale of iron ore extraction. The transportation of these resources is facilitated by the Duluth Missabe and Iron Range and Burlington Northern railroads, which cut through the central portion of the map.

South of the industrial activity, the environment shifts toward the glacial waters of Swan Lake and the Swan River. This southern half remains largely wooded, dotted with smaller bodies of water like Hart Lake and Snowball Lake. The settlement of Pengilly sits at the northern tip of the lake, serving as a residential anchor between the active mining districts of Greenway and the natural wetlands of Lone Pine.
