Rock Formations at Stone Mountain State Park

What types of rocks are found In North Carolina? What stories do they tell over the course of Earth's history? And what is a Granodiorite Pluton??
Join Emily and NC State Parks Geologist Randy as they talk about Stone Mountain. Stone Mountain is part of a 25-mile pluton, an igneous rock formed beneath the earth’s surface by molten lava. Over time, wind, water, and other forces gradually eroded softer layers of rock atop the granite block and exposed the outcrop we see today.
