What is a rock? How big is a boulder? Why are they pretty and heavy? It’s rock talk with a true enthusiast, the charming and beloved Geologist Schmitty Thompson. Schmitty walks us through different types of rocks, minerals, geological formations, roadside wonders, countertop crystals, stone skipping, and why you should stare lovingly into a pit of gravel. There were so many listener questions, we had to make this a two-parter people. So roll up a boulder, take a seat, and enjoy Schmitty’s Geology Corner. Also: losing my marbles.
