Creatures began arriving on Hilton Head over two and one-half million years ago.
When I set about developing this article on Hilton Head Island’s other than human population of creatures and critters and their introduction to the Lowcountry, I had no idea of the dimension of the objective.
I first learned that the Island itself evolved in two distinct segments. The north end of the island is a sea island dating to the Pleistocene epoch, a period begun 2,580,000 years ago. The south end is a barrier island that appeared as recently as the Holocene epoch, an era that began when the Pleistocene epoch ended, some 11,700 years ago. Broad Creek, which is a land-locked tidal marsh, separates the two halves of the island.
