The area under consideration, the easternmost Louisiana marshlands, is outlined on 

 Fig. 1. It is one of five areas into which the Louisiana coastal marshlands project has been 

 divided. The western part is low marsh, broken by many lakes, bayous, and a few natural 

 levee ridges. To the east are ten to fifteen miles of open water of Chandeleur and Breton 

 Sounds boumded on their seaward side by the low, discontinuous, sandy Chandeleur Islands, 



The area is a former subdelta of the Mississippi River and is now abandoned. Aided by 

 subsidence and eastward tilt, land is retreating before the attack of the sea.
