Devonian Fossil Gorge is a unique geological site where visitors can explore a former seafloor from approximately 375 million years ago. Long ago this section of Iowa was covered with a warm shallow sea and many fossils from that time period provide evidence of this past. Floods in 1993 and 2008 washed away several layers of soil and rock, exposing the fossils in the bedrock.
There are 17 points of interest in the park including the entry plaza, which interprets the site and features displays related to the nearby dam, the fossils, and the floods. A map detailing all of the sites is available online and at the park's entry plaza.
