Stratigraphy Example: Waites Island

Waites Island Environments

Waites Island is an undeveloped barrier island located at the northern end of the South Carolina coastline.  The ~5 km long island is bounded by Little River Inlet to the north and Hog Inlet to the south.  A transect from the sea to the landward will encounter the following environments: beach, dune, a brackish water (intermediate between salt & fresh water) wetland, a landward beach/dune ridge system and marsh.  This older landward ridge system was likely formed at different times since 4000 years ago, with the current beach potentially forming seaward of the landward ridge within the last 300 years.  Since sea level is currently rising, understanding these historical changes may allow for better decisions on how to manage shoreline retreat.
