Geology students explore Upper Peninsula

This October, students enrolled in the Physical Science Department’s geology program joined students from Grand Valley State University and Muskegon Community College in the Upper Peninsula to explore evidence of our continent’s tumultuous beginning. Students used their geology skills to study 1-2 billion year-old rocks exposed in the Marquette area. They moved from the “sea to the shore” as they identified submarine lava flows, beach sands now faulted and tilted to a near-vertical angle, ancient life forms called stromatolites, and stacked beds of pure iron ore deposited in Precambrian seas. Students returned to the Lower Peninsula with backpacks full of rocks and bellies full of pasties.
