Rocks hold fascinating stories that can be deciphered by looking at their formations in various places like grocery parking lots, majestic outcrops in the wilderness, or road cuts. These earthly formations provide insights into the planet's history spanning billions of years. Observing rocks leads to pondering their origins, whether they were deep within the earth or on a beach, or if a dinosaur once walked on them, provoking curiosity and awe. The distinction between boulders, pebbles, rocks, and geological formations lies in the earth material's composition of minerals.

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.
