Abstract
The Mississippi delta is a complex consisting of the recent bird-foot delta and several fossil deltas now modified by the isostatic downwarping of this region localized on the edge of the active Gulf-geosyncline. Chenier Islands are stranded sand beaches in a marshland environment. Initially formed along the sea shore they indicate former coast lines. On the chenier plains of south-western Louisiana hurricanes have significant geomorphic effect. In the paper the interplay between chenier formation and delta development is discussed based on the results of Rich. J. Russell's research work. The description utilizes the author's observations from field trips in 1959 and 1963.
