In this episode, Dannelle Gay takes you beneath America's Dairyland to explore the mysterious, magical, and sometimes muddy world of Wisconsin's caves.

Karst Topography: Wisconsin's limestone and dolomite dissolve slowly in water, forming tunnels and caverns over millions of years.
Glacial Influence: Melting Ice Age glaciers carved valleys and exposed cave openings, making them accessible today.
The Driftless Region: This untouched geologic pocket in southwestern Wisconsin remains rich in caves, springs, and underground streams.
Dress in layers — underground temps stay around 50°F year-round.
Wear sturdy shoes with traction.
Bring a flashlight or headlamp, especially for dimly lit tours.
Don't touch rock formations; even small oils from skin can stop mineral growth.
Book ahead during summer or fall weekends — popular tours fill up fast.
Check accessibility — some caves have stairs or tight passages.
Dr. Evermor's Forevertron (near Cave of the Mounds) – whimsical metal art park for post-cave inspiration.
Blue Mound State Park – hike the observation tower for panoramic views.
Maribel Caves Park Trails – great for fall colors and waterfall photography.
Apostle Islands Cruises – boat tours of the cliffs and sea caves if kayaking isn't your speed.
