 Field State Park overlook, areas used to corral 

 horses and an exercise track used to 

 rehabilitate race horses have been slow to

irregular circles in the 1953 aerial photo 

 (Figure 2.7) were filled with sands washed 

 from the beach and dune during the 1983 

 storm. Standing water accumulated east of the 

 road to the overlook, allowing establishment 

 of brackish marsh vegetation in that area.

 photograph shows the estuary after nearly 5 

 months of closure to tidal flushing (from U.S. 

 Army Corps of Engineers). Note patches of 

 cordgrass mortality (C) near tidal creeks.
