Houghton and Hancock anchor the northern edge of this copper country survey, where the industry's footprint is visible through the Isle Royale Mine and Old Superior Mine. The landscape is defined by the heavy infrastructure of the Duluth South Shore and Atlantic and Copper Range railroads, which hug the shores of Portage Lake and Pike Bay.
