Plaquemines Parish is where the Mississippi River stops being a river and becomes something else — a braided, shifting, sinking delta that dissolves into the Gulf of Mexico. The last 70 miles of LA-23 trace this transformation. The road narrows. The levees rise. The land between them gets thinner until there's more water than solid ground on both sides.
This is where La Salle stood in April 1682 and claimed everything the river drained for France. That claim — made at the edge of a continent, in a marsh — created Louisiana. The monument marking the approximate site is remote and understated, which is fitting. The landscape makes the argument better than any plaque.
Bar pilots have guided ships through the river's mouth since the 1700s. Pilottown, near Head of Passes where the Mississippi splits into its three main channels, was once a functioning community of pilot houses on stilts over the water. Today it's largely abandoned but still operational — pilots still board ships here for the transit upriver to New Orleans.
Venice, at the end of the road, is where the fishing charters launch and the oil service boats dock. It's the last inhabited place on the river. Beyond it, the bird's-foot delta extends another 20 miles into the Gulf — a landscape visible only from the air or by boat.
The delta is disappearing. Coastal erosion, subsidence, and sea level rise are consuming Plaquemines Parish at a rate of roughly a football field every 100 minutes. Fort Jackson has been submerged. Entire communities have relocated. The Orange Festival celebrates what remains of a citrus industry that saltwater intrusion is steadily destroying.
What La Salle claimed in 1682 is dissolving back into the Gulf. Plaquemines Parish is where you can watch it happen.
