Copper production has gone on around Michigan's Keweenaw Peninsula for over 3,000 years. Native Americans first engaged in the practice these many millennia ago, and by the 1840s, there were mineral rushes going on in the area. Many thousands of people came in search of copper, and by 1985, over 14 billion pounds of copper were produced from the region. This remarkable digital collection crafted by Michigan Technological University brings together many historical photographs that document the district. All told, there are over 3,500 items here, and visitors can search the holdings by keyword or more detailed parameters. Visitors also have the option of creating their own personal web album with items of interest to them. The Subject Browse tab is a good way to delve into the collection, as visitors can look over anything from Accidents to Woody Plants. This collection illuminates the region and the ways in which the copper industry transformed this rural and bucolic environment.
