It is only “wafer-thin” (“Monty Python”) — made of corrugated steel, this wafer-thin wall over 2,000 feet long, driven into the sand on Cap’n Sam’s Spit.

Maybe driven down to hell, with me under it.

But the diamond back terrapins’ only nesting site on Kiawah Island is on this narrow part of the spit. It is only wafer-thin, too.

What is going on at the spit is confounding. However, the bottom line is that nature will win with a little help from those who care.
