Get ready to rock—literally!
Step into the magical underground world of Cave of the Mounds for a night of geologic fun and live rock music from Melissa Kieler Music echoing through the formations. Let curiosity get the better of you while you drink and dance; this night is all about the science of stone!
Geode & Sluicing Talks – Take a crack at nature’s lottery and see what treasures lie within our geodes, or dig down into your gold-panning roots and sift away sand and silt to reveal gems and fossils to take home with you!
Ask a Geologist – How do mountains form? How does Yellowstone work? What really killed the dinosaurs? Bring your questions and curiosities with you: our staff geologist awaits to give you answers and explanations for the wonderful, rocky world around us!
Get your tickets now — this party will be a blast from the 4.6 billion year past!
