Point (Biloxi quadrangle), dunes that had been 4.5 to 6 m (15 to 20 ft) NGVD 

 were eroded to 1.5 m (5 ft) NGVD. 



On Dauphin Island (Biloxi quadrangle) in Mobile County, the south side of 

 the island, fronting the gulf, has a broad, wel 1 -developed beach and sand 

 dunes that rise to 12 m (40 ft) NGVD. 



The atlas maps delineate where dunes of any description are found within 

 the study area. In order to map the exact location of those few truly active 

 dunes, a new large-scale mapping exercise would have to be undertaken.
