The "Crescent" isn't sinking. Apparantly there's a rocky outcrop down there that keeps it suspended above sea-level. However, the Mississippi River has accumulated enough silt in its bed that it has risen higher than the Crescent ~ hence, the need for massive levees along the river.

Everything else down there is sinking.

Thanks -- interesting.
