Copper Harbor in Keweenaw County, Michigan — The American Midwest (Great Lakes)
"A Rallying Point for Copper Adventurers"
A Pioneer, 1846
By the mid-1840s Copper Harbor became a rough and tumble mining camp, where one visitor recalled, “the restraints of civilization sat loosely on men.” Boats of every description crisscrossed these waters carrying prospectors and supplies. The Pittsburgh and Boston Copper Harbor Mining Company sank the first commercial mine near the present lighthouse.
Copper Harbor and other pioneer settlements relied on lake transit for transportation, communication and supply. Weather conditions cut them off from the outside world six months of the year.

1. Pittsburgh and Boston Copper Harbor Mining Company. The Pittsburgh and Boston Copper Harbor Mining Company was one of the earliest copper mining concerns on the Keweenaw Peninsula. The company mined copper-bearing silicates at Copper Harbor between 1843 and 1847, until operations were transferred to the much more profitable Cliff location. The workings at Copper Harbor were sizable; at times the company employed up to 70 men. (Submitted on July 29, 2020, by Cosmos Mariner of Cape Canaveral, Florida.)

3. A Short History of Copper Mining. The Cliff Mine was near Eagle Harbor, 19 miles west of Copper Harbor. Huge pieces of metal, some weighing more than 50 tons, were discovered where they had been deposited. They lay deep beneath the surface, undisturbed by the glaciers. In 1849, the Cliff hit rich vein rock. Pure copper masses, some weighing 100 tons, were chiseled, hammered, blasted, cut in pieces and hauled to the surface bit by bit.
