Riverside Dr. at floodwall Interpretive Center with walk to Devonian fossil bed along rapids on the Ohio River.
Around 387 million years ago this area was a shallow tropical sea. Living in the waters were countless corals, sponges, mollusks, and now extinct brachiopods and echinoderms. Over time, as these animals died, they became buried in layers and layers of sediment that helped to fossilize them. As the Ice Age glaciers retreated, the numerous fossil beds became visible, seen most heavily in the park location, but throughout the Ohio River Valley.
American history is vast in the park, and is discussed at the visitors center. George Rogers Clark established the first English-speaking settlement in the Northwest Territory in a part of the park, in 1778. Aaron Burr trained military troops in the area for a proposed Mexican invasion. William Clark and Meriweather Lewis set off on their landmark journey from the area.
The Falls consist of a series of rapids which were formed by the water flowing over an island of fossil beds. Now, only a small set of rapids are visible, due to the building of the McAlpine Dam in the 1920s. More then 600 species of fossils are found within the park, including hundreds of brand new species.
Over 270 species of birds (herons, egrets, waterfowl, osprey, falcons and the occasional bald eagle) and 125 species of fish (including the primitive paddlefish, striped bass, sauger, white bass, crappie and catfish) are found in the park.
