In the floods of 1993, water exceeded the capacity of Coralville Lake's dam. Those waters caused a great deal of damage in the surrounding area. But at the foot of the dam, an incredible discovery was unearthed. 

The Devonian Fossil Gorge is an amazing time capsule of fossils dating back 375 million years, a time when Iowa was beneath the Panthalassic Ocean. 

200 million years older than dinosaurs, scattered across the gorge floor are the fossilized remains of brachiopods, corals and crinoids, prehistoric sea creatures whose unique designs will enrapture any visitor. 

From natural disaster to irreplaceable geologic treasure, the Devonian Fossil Gorge is waiting to transport you to a version of Iowa where no human ever set foot.
