Michigan's Upper Peninsula might not be the first spot you think of when someone says "volcano," but maybe it should be! Around 1.1 billion years ago, a rift volcano started producing massive amounts of lava. That volcano (with the help of some glaciers around 10,000 years ago) formed some of the Upper Peninsula's most iconic landscapes--including Lake Superior! 

GUESTS: 

Erika Vye, geosciences research scientist at the Great Lakes Research Center at Michigan Tech University

Daniel Lizzadro-McPherson, geospatial research scientist at Michigan Tech University
