Earth Day is a day that is intended to inspire awareness and appreciation for the planet’s natural environment. The Ohio Statehouse is an ideal place to celebrate Earth Day, as the building is a natural classroom and laboratory to view fossils.
The Ohio Statehouse is constructed of Columbus Limestone. Columbus Limestone is of the Middle Devonian age and was named for the city where it has long been quarried. The Columbus Limestone crops out in a north-south line from Kelleys Island in Lake Erie to south of Columbus. The limestone was formed in a clear, shallow, tropical sea that covered the state almost 400 million years ago. Fossils of marine animals are abundant in the Columbus Limestone and can be seen throughout the Capitol Square complex.
