Millions of years ago (1.5 to 28 to be exact), the South Carolina coast was underwater. The ocean went about 100 miles inland of today’s coast. Prehistoric marine animals like Megalodon sharks and whales left behind fossilized teeth and bones. Once the water retreated, the area became a prehistoric jungle and a final resting place for giant beavers, Saber-toothed tigers, and cave bears.
In more recent times, the rivers of this region were like highways. Artifacts from Native Americans and Colonial times can be found in Cooper River, too.
Like panning for gold, the Cooper River washes away mud and lets deposits of fossils and artifacts settle on the bottom.
For adventurous experienced divers, it doesn’t get much better than exploring the depths of the Cooper.
