The lodes of native copper found in the Lake Superior region presented new opportunities for investors and miners alike. Making these opportunities pay required the unique challenges presented by the region’s remoteness and unique geological formations to be overcome. A primary way in which these newly emerging companies overcame these challenges was through successful vertical integration of the copper refining industries. Smelting came to the region early, but met with little success as the workers first needed to retool their skills and experiences to the demands of the region’s mineral deposits.

The Calumet and Hecla Copper Mining Company in Houghton County, Michigan, was established in 1865 and closed its doors in 1968. This company was a major contributor in developing secondary copper processing and used these methods to produce copper even when its underground mines were closed. C&H built its own electrical transmission system that could have rivaled many during its time. This allowed the company to have the ability to produce and control its electrical network and expand, but it had major environmental effects. Polychlorinated biphenyl compounds (PCBs), used in transformer oil and other components were produced between about 1930 …

Dissertations, Master's Theses and Master's Reports
Michigan Technological University has been performing archaeological and historical surveys at Fort Wilkins Historic State Park as part of a multi-year contract since 2013 with each year’s work focused on different properties held by the Park. The 2015 field season focused on the 6 acre Copper Harbor Range Lighthouse (20KE33) property immediately west of Fanny Hooe Creek resulting in the identification of eight archaeological features through a combination of pedestrian survey, shovel pit testing, and excavation. Among the features identified are the Astor House (20KE83), an early hotel in the region which was noted in the writings of travelers visiting …
