Karst Interactive Exhibit by the Minnesota Pollution Control Agency
July 28 – August 10, during regular library hours
Water in southeast Minnesota flows through some of the most unique geology in the world, known as karst. In karst geology, the erosive effects of water have sculpted thick layers of limestone over thousands of years. The landscape is characterized by abundant sinkholes, springs, caverns, and underground waterways — it’s like the Swiss cheese of rock. Water in the karst region mixes above and below ground; pollutants on the surface can easily reach groundwater used for drinking.
This interactive exhibit created by the Minnesota Pollution Control Agency includes components that show:
- How water moves through karst geology
- The challenges related to keeping groundwater safe for drinking
- How people can help protect water resources
The Clean Water Fund, as part of the Clean Water, Land and Legacy Amendment, provided funding for the project.
- Tuesday, August 2, 6:00pm: Karst Science for Families – Miss Meg will lead families through a conversation about karst with hands-on activities to show how it forms.
- Thursday, August 4, 6:00pm: Driftless Area / Karst Presentation – Sara Holger, Lead Interpretive Naturalist of Whitewater State Park, will discuss the natural history of this region and how it relates to its unique plants and animals.
