From 7,000 years ago to the 1900s people mined Keweenaw copper. Native peoples made copper into tools and trade items. Investors and immigrants arrived in the 1800s in a great mineral rush, developing thriving industries and cosmopolitan communities. Though the mines have since closed, their mark is still visible on the land and people. There is much to see and do on the Keweenaw Peninsula. In addition to exploring the history of copper mining, numerous recreational opportunities are available in the area. In the summer hiking, canoeing, kayaking fishing, camping and biking are popular activities. During the winter, the normally abundant snowfall make this a prime area for snowshoeing, cross-country and downhill skiing, ice fishing and snowmobiling.
