S3 E8: Seth Stein, Professor of Earth and Planetary Sciences at Northwestern University

The rock that rings Lake Superior has fascinated visitors for centuries. From the most common Basalt, Granite and Rhyolite to Agates and the popular “Yooperlite” that glows fluorescent under black lite, the shoreline makes a rock hound’s paradise. When it comes to “Reading the Rock” and explaining the geologic story, there’s none better than Professor Seth Stein from the Department of Earth and Planetary Sciences at Northwestern University. In this episode of the Lake Superior Podcast with Walt Lindala and Frida Waara, he shares details about the MId-Continent Rift and how all 5 National Parks on the Lake share evidence of this geo-heritage. Sponsored by Cafe Imports, a Minneapolis-based importer of fine, specialty green coffees.
