When you're driving back to the island on Main Road and cross the Limehouse Bridge, one of the twentieth century's engineering marvels spreads out to the right and left below. It's the Atlantic Intracoastal Waterway, of which Charleston Harbor and its feeder waterways are a part. Stretching from New Jersey and around the Florida Keys to Brownsville, Texas, the AIWW is a patchwork of lakes, rivers and dredged canals that allows both leisure and commercial boat traffic to travel the eastern seaboard sheltered from more dangerous open ocean, following the famous Magenta Line on navigational maps developed by the National Oceanic and Atmospheric Administration (NOAA).



Although it's a twentieth century development, the roots of the Waterway go back as far as the early eighteenth century, when a fledgling United States government set out to facilitate waterborne trade among the states, still separated by thousands of acres of undeveloped wilderness from trading and shipping centers like Charleston and Savannah in the south and Boston and New York in the north. Part of the southeastern portion of the Waterway, for example, is along the Great Dismal Swamp Canal which crosses the border of Virginia and North Carolina, dug by enslaved labor along a route first surveyed before the Revolution by a young George Washington.

But it wasn't until the early 1900's, as motorized boating became practical, that the first charts were developed and published in a booklet called The Inside Route. It still required a good deal of by-the-pants boating until after World War Two, when the federal government invested millions of dollars in re-surveying, re-dredging, new charts, and a series of mile markers along the entire route of the new Magenta Line. The last section of the AIW was completed in Brownsville in 1949.


Today, the Waterway is busy all year-round with commercial shipping heading for coastal ports from inland mining and manufacturing sites, along with leisure traffic traveling south for the winter and north for the summer - and, of course, for SINHG members, who have enjoyed a day on the water as one of our SINHG Trips for members, exploring this blue thread connecting the Lowcountry to the wider world.


With Halloween approaching, Lowcountry ghosts are stirring, from downtown Charleston to right here on Johns Island, where two sites have a long tradition of spectral sightings.

The Angel Oak seems especially attractive to spirited presences. As recently as 2008, a young married couple made a moonlight visit to the Oak, under which they'd been married some months earlier, and reported seeing glowing lights amid the ancient tree's branches. The spirits became threatening, turning into flaming, mask-like faces, when the husband tried to carve his initials on the tree with a penknife. It wasn't until the couple hastily retreated that the faces disappeared and the star-like lights that they'd seen earlier returned.


Fenwick Hall, before restoration

Another, more unfortunate, couple are said to haunt the grounds of Fenwick Hall, the Georgian-style plantation home along today's Maybank Highway, built in 1730 by John Fenwick and inherited and enlarged by his son Edward. Famous for his racehorses and his Johns Island Stud, Edward became enraged when his beautiful young daughter Ann eloped with a Fenwick groom, hardly the socially acceptable union Edward wanted for Ann. The couple was found hiding in a log cabin in the marshes surrounding the estate. It's said that Edward ordered the groom mounted backward on a horse with a noose around his neck, and then cruelly forced Ann to strike the horse on the haunches, thus hanging her lover. Both Ann and the groom are said to walk the grounds of the former plantation; more alarmingly, the groom is said to be headless.

Lavinia Fisher, Charleston's first serial killer

Downtown Charleston is, of course, infested with ghosts. The restless spirits of John and Lavinia Fischer, the city's first serial killers, were hanged at downtown's Old Jail, where they are said to appear on certain nights. The couple owned a tavern and inn in what is now North Charleston, where they reportedly offered particularly wealthy guests poison-laced tea before robbing them and disposing of their bodies in the basement.


Actor Junius Booth, still appearing in Charleston

The Dock Street Theater has its own pair of ghosts - a young prostitute who threw herself off the second floor balcony of the building during its time as a hotel in the early 19th-century, sometimes joined by the ghost of famed actor Junius Booth, who frequently trod the boards at the theater during national tours of his Shakespeare recitals. Even though Junius died on a riverboat in Louisville, Kentucky, it's said his fondness for the old theater and admiring Charlestonian audiences draws his spirit back to the Holy City.

While replenishment operations are underway to help preserve our island's beaches, the near future may bring the more ambitious relocation of Captain Sams inlet at the northeastern tip of North Beach, usually a reliable spot for dolphin watching and for enjoying our lively populations of shorebirds. But it hasn't always been so welcoming, for this is a constantly shifting coastal geography shaped and re-shaped by wind and water at the confluence of the Atlantic Ocean and the Kiawah River. At many points in its history, there was no beach at all here.

Captain Sams Inlet, dividing Seabrook and Kiawah islands, is a highly visible example of how our beaches and dunes are continually on the move, in some years migrating more than 300 feet. The inlet has shifted position scores of times in the past 150 years, at one point migrating as far to the southwest as present-day Boardwalk #1, with no walkable, dry-sand beach to the northeast as erosion carried sand away to the south.

During Seabrook's early days of development as a planned coastal community, seawalls and stone revetments were only partially successful in preserving the beachfront, and most of those structures were destroyed during Hurricane David in 1979 - severely enough that construction on the original Beach Club had to be halted and the only usable beach was reduced to about two-thousand feet south of Boardwalk #1.

The damage was severe enough to spur SIPOA, and the the towns of Seabrook and Kiawah islands, to adopt a major relocation of Captain Sams Inlet in 1983 as a way to slow erosion which had been taking sand away from Seabrook's shoreline. It was the first of three such relocations, with two more following in 1996 and in 2015, involving cutting a new inlet entry to the northeast and blocking the old one to the southwest.


The result since the first relocation has been the preservation of as much as fifty acres of additional beach and marsh on Seabrook, providing crucial habitat for shorebirds like the endangered piping plover and building up protective dunes and water-absorbing marshland against storm surges. The inlet's position and ecology is monitored on an annual basis. The next time you visit Captain Sams Inlet, remember that you're, very literally, walking on shifting sands.
