This video explores Lake Superior's extraordinary, ancient volcanic history and serves as an introduction to a learning module on the topic developed by Hamline University's Center for Global Environmental Education. Featuring geologist Jim Miller, the video connects current eruptions in Hawai'i and plate tectonics in Iceland with millions of years of volcanic activity that happened via North America's midcontinental rift a billion years ago.
