Copper Country is highly unusual among mining districts in that the copper mined was predominantly in its elemental ("native") form, rather than in the form of compounds (mostly oxides and sulfides) that form the basis of the copper ore at almost every other copper-mining district.
Douglass Houghton, the State Geologist of Michigan in the mid-1800s and later to become mayor of Detroit, reported on the copper deposits in 1841. The first successful copper mine, the Cliff mine, began operations in 1845, and spurred by venture capital from Boston and other East Coast investors, many other mines quickly followed. Mining of the most productive deposit, the Calumet conglomerate, began in 1865. Mining took place along a belt that stretched about 100 miles southwest to northeast.[2]
While mining in Copper Country continues to this day, it is on a much smaller scale than before, with tourism and logging having taken over as the area's largest industries.
Immigrants to Copper Country
Initially, Irish, Cornish, French-Canadian and German immigrants came to mine copper on the peninsula. They were followed by large numbers of Finns, Swedes, Danes, Sámi and Norwegians who immigrated to the Upper Peninsula, especially the Keweenaw Peninsula, to work in the mines. The immigration of people from Finland peaked from 1899 to World War I. Slovenes, Croatians, and Italians emigrated from about 1880, the first two groups sometimes called Austrians as their homelands were then part of the Austrian Empire. Polish people also were attracted to this successful mining area. Thus the pattern in this boom period was first the Native Americans and people from the British Isles, French Canada and Western Europe, followed by people from the Nordic countries, and then by people from Southern and Eastern Europe. The Finns in particular stayed on and prospered even after the copper mines closed, while most moved on to other mining areas or homesteaded in other Midwestern states.[3]
Popular tourist destinations include the cities of Copper Harbor, Houghton, and the Porcupine Mountains with Lake of the Clouds. Snowmobiling is very popular in the winter, and snowmobile trails are found in most areas.
Institutions of higher education include the former Finlandia University in Hancock, founded in 1896 as Suomi College (closed in 2023), and Michigan Technological University in Houghton, originally established in 1885 as the Michigan School of Mines. Finlandia University was affiliated with the Evangelical Lutheran Church in America, reflecting the spiritual heritage of the region's many Finnish immigrants. Michigan Tech was founded in response to the needs of the copper mines.
Industrial pollution leftover from the former mining operations remains a significant problem in the region. Copper processing produced enormous quantities of stamp sand as a waste product, which was often stored in large, unsecured piles near the coast. In the town of Gay, Michigan, stamp sands from a former mill have escaped into the lake and gradually moved South along the coast, burying the natural shoreline, creating new land, and obstructing piers and waterways.
Winter snowfall
The Copper Country averages more snowfall than any part of the United States east of the Mississippi River, and more snowfall than any non-mountainous region of the continental United States.[4]
