Brian will introduce participants to the basic types of rocks and explain how they form, what clues they hold about ancient environments, and why Door County’s geology is so unique. Learn how limestone, dolomite, and glacial deposits shape the peninsula’s landforms, influence soils and plant communities, and even affect how water moves through the landscape.

This approachable, hands‑on introduction to geology will help you see familiar shorelines, bluffs, and trails in a whole new way. Whether you’re a curious beginner or someone who’s always wondered what’s “beneath your boots,” this program offers a solid foundation for understanding the natural history written in stone across Door County.
