About this map

Iron mining dominates the northern landscape of this Itasca County region, where the massive operations of the Patrick Mine, Hawkins Mine, and Snyder Mine have reshaped the terrain with extensive mine dumps and tailings ponds. The settlements of Nashwauk, Cooley, and Pengilly are tightly integrated into this industrial corridor, linked by the Great Northern and Duluth Missabe and Iron Range railroads.

South of the heavy industry, the map reveals a starkly different water-rich environment centered on Swan Lake and the Swan River. This area preserves the natural drainage of the Mesabi Range, featuring numerous named water bodies like Snowball Lake, Oxhide Lake, and Hart Lake. The juxtaposition of massive open-pit mines such as the Halobe Mine against these pristine lakes demonstrates the intensive resource extraction era of the early 1950s.
