South of Lake Superior, your ship will cross the Keweenaw Peninsula via the eponymous waterway along the Portage River. This stretch of land located in the north of the State of Michigan is part of the Copper Country, home to large mines run by the Native Americans over 5,000 years ago and rediscovered thanks to their descendants at the beginning of the 18th century. A copper rush ensued, with waves of immigration from Finland and Northern Europe. The river separates the towns of Houghton, in the south, and Hancock, in the northern part also known as Copper Island or Kuparisaari by the Finnish immigrants. So, crossing Keweenaw also means looking back over the region’s history.
