Geology students from GRCC, GVSU take field trip to Upper Peninsula

On a cold and wet October Saturday, geology students from GRCC stepped 2 billion years into the past! Some of the oldest rocks in the world are exposed in the Upper Peninsula of Michigan and are evidence of our continent’s tumultuous beginning. A joint GVSU/GRCC field trip provided students with an opportunity to put their geology skills to good use identifying and interpreting rocks from a vast array of outcrops. They moved from the “sea to the shore” as they identified submarine lava flows, beach sands now tilted to a near-vertical angle, ancient lifeforms called stromatolites, and stacked beds of pure iron ore that fueled Michigan’s automobile industry. By the end of the day the group was a little damp but happy with their shared experience and U.P. rock samples!
