Welcome Educators! 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 mineral rush. A thriving industry developed. Though the mines have since closed, their mark is still visible on the land and people. Here you will find field trip guidance, lesson plans, a list of guest speakers, online galleries & videos, a suggested reading list and announcements for teacher workshops.
