Evolution is a fundamental principle in understanding the diversity of life today and throughout Earth’s geological history.

    Celebrate National Fossil Day at the Falls of the Ohio State Park with a series of special fossil bed hikes, reduced admission for the Interpretive Center, guides on the collecting piles, children’s activities and more!

  The outer fossils are one of the world's amazing excursions to see Devonian fossils in their natural "habitat." We can only offer hikes in the late summer and fall when the upper gates of the McAlpine Dam are closed.
