The Keweenaw Peninsula is the site of the most extensive known deposits of native copper in the world. Occurring here in relatively pure form, the red metal could be broken out of the rock and worked to make a wide variety of products, from jewelry and tools by its earliest miners to coins and electric wire by its final generations. Keweenaw copper was mined for approximately 7,000 years, from 5000 BCE until 1968. During the period for which records were kept, 1840–1968, more than 11 billion pounds (5 million metric tons) of copper were mined here. During the peak production years of World War I, 1916–1917, the annual copper yield reached a maximum of 270 million pounds (125,000 t).
Two ethnic groups, the Cornish and the Finns, are especially important in the heritage of the Keweenaw National Historical Park. When news of the region's rich native copper was first widely published in the 1830s, many families from the English county of Cornwall immigrated to the Upper Peninsula, bringing the Cornish pasty and their region's knowledge of hard-rock mining with them. Several park Heritage Sites, including the log cabin village of "Old Victoria," recall Cornish heritage in the region.
Later in the 1800s, many families from Finland emigrated to the United States. Until 1918, Finland was a colony of Russia. A large percentage of these Finns settled in the Western Upper Peninsula because of perceived similarities between their old and new homes, and found work in the Keweenaw. Finnish saunas can still be found throughout the area. Several park Heritage Sites, including the "Hanka Homestead", recall the Finnish influx.
