Wisconsin's Official Mineralogical Museum

The Weis isn’t your grandfather’s museum full of dusty glass cases, although we’ve got some really old stuff here!Every Rock Tells a Story

Imagine a museum where you can make an earthquake, walk through a mine tunnel, shoot off a quarry blast, touch a dinosaur bone, and make a rainstorm. That’s the Weis!

And everyone from the advanced collector to the youngster who just started picking up rocks will be amazed at the marvelous minerals and fabulous fossils on display.

While you’re having lots of hands-on, interactive fun, you’ll discover that there were once volcanoes, mountains and tropical reefs right here in Wisconsin. In fact, you’ll learn that every rock tells a story, and you can read them yourself!
