The Devonian Fossil Gorge is our star attraction. It was created by the Flood of 1993 and expanded by the Flood of 2008 when water topped the emergency spillway. The overflow washed away tons of soil, huge trees, and part of our road. When the waters receded the 375-million-year-old fossilized Devonian ocean floor was revealed. Visitors start their stroll back in time at the Entry Plaza, making their way down into the gorge to find thousands of fossils laid out at their feet!
