8th, Mines and Minerals of Southern Illinois, 2:00 to 3:00 PM. 

A program about an area that is famous for fluorite and other minerals with a mining history dating back to the 1840s. The park's mineral collecting pile is loaded with small pieces from this area that visitors can pick up and take home as a souvenir. Alan Goldstein will present on why that small area produced the lion's share of spectacular minerals that grace private collections and museums around the world. The most famous mines of the past 80 years will be described through photos and stories. Regular Interpretive Center admission applies.


11th, Understanding Evolution, 2:00 to 4:00 PM.

Evolution is a fundamental principle in understanding the diversity of life today and throughout Earth’s geological history. This program, a volunteer training class open to the public, explores what it is and aspects of a uniquely American controversy. Regular Interpretive Center admission applies.


18th, Origin of the Ohio River During the Ice Ages, 2:00 to 4:00 PM.

Did you know the Falls of the Ohio is one of the youngest geological features in the United States? The Ohio River we know today did not exist before the Ice Age. Dr. William Andrews, the Kentucky Geological Survey geologist who is featured in our exhibit on the birth of the Ohio River and the origin of the Falls of the Ohio, will present on the nature of the landscape before the Ice Age and how glaciers dramatically reshaped the region, exposing the Devonian fossil beds in the process. Regular Interpretive Center admission applies.


22nd, Family Nature Club – Wonderful Geodes, 2:00 to 3:00 PM (Interpretive Center lobby)

Bring your kids to explore geodes – fascinating spherical rocks filled with crystals. What makes a geode different from other types of crystal pockets? We will look at geodes and the wonderful crystals inside and give examples away. Weather permitting, we will try to crack open a few. You may bring your own geodes for identification. We will look at small geodes up close with a microscope. A public program on the minerals inside geodes follows at 3:00 PM. Free. (Doesn’t include admission to tour the museum.)


22nd, Discovering Geodes, 3:00 to 4:00 PM

25th, Freshwater Mussels, 2:00 to 3:00 PM

The Ohio Valley has some the greatest diversity of freshwater mussels in the world. Yet they are in peril, with dams and pollution reducing their number and causing a number to become extinct. Learn about this overlooked by fascinating creatures that one time dominated the button industry in communities like Madison, Indiana. Fish and Wildlife biologist Brant Fisher is our guest presenter. Regular Interpretive Center admission applies.


28th, Falls overview, 2:00 to 4:00 PM

Paul Olliges, a Falls of the Ohio State Park “volunteer of the year” will lead you through an overview of the history of the Falls, from fossils to the engineering feats that made the Falls of the Ohio what it is today. Regular Interpretive Center admission applies.
