Copper Harbor is an unincorporated community and census-designated place (CDP) located in Keweenaw County in the U.S. state of Michigan. It is located within Grant Township. The population of the CDP was 136 as of the 2020 census. The community is located at the northern tip of the Keweenaw Peninsula. Copper Harbor is also the northernmost permanently populated community and northernmost point of mainland in the state of Michigan. Due to its natural environment and surroundings, Copper Harbor is marketed as an all-season tourist destination and also contains Fort Wilkins Historic State Park. History The Keweenaw Peninsula and the area that would become the Copper Country was home to the Ojibwe people prior to European settlement. In 1836, the Upper Peninsula was officially ceded from the Native American Chippewa to the United States following the signing of the Treaty of Washington. The treaty was signed in the national capital, Washington, D.C., by Henry Schoolcraft and Native American representatives from the Ojibwe and Odawa nations. Copper Harbor was host to the first mineral land agency throughout the entire Lake Superior District. Captain Walter Cunningham was appointed by the United States Department of War to act as a Special Agent to the area. As soon as wayfinding was established in the spring of 1843, Cunningham had come to the area and opened his office, which was thereafter named the "Government House". It was positioned on Porter's Island, a small rocky island just opposite of present-day downtown Copper Harbor. The Pittsburgh and Boston Copper Harbor Mining Company, formed by John Hayes of Cleveland, Ohio, began excavating some pits near Haye's Point in Copper Harbor in 1844. It was a small development at first, but its mine was modern for its time, and the company struck it rich in 1845. The Pittsburgh and Boston mine operations were some of the very first in the state of Michigan. A few years later, the Central Mine, Cliff Mine, and others were opened and became successful. However, by 1870 the copper resources in the community had been largely worked out. The community of Copper Harbor was listed as a newly-organized census-designated place for the 2010 census, meaning it now has officially defined boundaries and population statistics. Etymology The name of the community, Copper Harbor, alludes to the former use of its harbor as a port for shipping copper mined from local deposits during the mid-19th century. Transportation
