After floating through the hilly Piedmont, you arrive at the Sandhills of South Carolina. Between 55 and 100 million years ago the sea level was higher and the coast was farther inland. Marine fossils and beach sand remain as evidence of the ancient beachfront in the Sandhills. Over millions of years, the sea level dropped and by 10,000 BCE humans occupied the central area of the state.
