The Keweenaw Peninsula (/ˈkiːwᵻnɔː/ KEE-wi-naw, sometimes locally /ˈkiːvənɔː/) is the northernmost part of Michigan's Upper Peninsula. It projects into Lake Superior and was the site of the first copper boom in the United States. As of the 2000 census, its population was roughly 43,200. Its major industries are now logging and tourism, as well as jobs related to Michigan Technological University and Finlandia University.
