St. Louis River Field School

Virtual and homeschool learners in grades 6-8 are invited to take learning outside with science and education staff from the Reserve. Taking place at different locations along the St. Louis River, including Wisconsin Point and the Superior Municipal Forest, each of these monthly, hands-on experiences will provide a place for students to unplug outdoors and gain an appreciation of the St. Louis River.
