Pond

The water in this man-made pond comes from a spring located on the eastern edge of the pond, and if you listen closely, you may even hear water bubbling up from the underground aquifer!

Dolamite Cliff

Our dolomitic bedrock was formed around 450 million years ago in the Ordovician period, when Illinois was a warm, shallow ocean.
