They say if you don’t like the weather in Illinois, wait 10 minutes and it will change. Similar to its volatile weather, Illinois has experienced vast geological change - albeit on a scale of millions of years! Geologic evolution continues today, but at a very slow pace. Naturalist Lisa O’Brien will explain the changes Illinois has undergone, much of which has created our bedrock and soils. She will highlight the state's current glacial topography and ecosystems and describe forest preserves where you can experience our geological phenomena up close.
