Diagram of the Cincinnati Arch
Mary Mae learns about the Cincinnati Arch from her fifth grade teacher in Mary Mae and the Gospel Truth. Here we see how the Ordovician strata is exposed. This is the strata on which the city of Cincinnati rests. It was once a warm, shallow sea basin, filled with trilobites and other sea life, but as continents shifted, the land was forced up. Now we have access to the fossils of that period, which ordinarily would be buried.
