The U.S. Gulf coastal states have a variety of confirmed and suspected impact craters and structures. Texas has the most confirmed craters and structures (Marquez, Odessa, and Sierra Madera) and suspected impact features (Bee Bluff, Hico, and an unnamed structure). Among the other Gulf coastal states, the record is as follows: Louisiana (Brushy Creek – suspected), Mississippi (Kilmichael – suspected), Alabama (Wetumpka – confirmed), and Georgia (Woodbury – suspected). This paper reviews these confirmed and suspected craters and structures and presents some new findings about some of these features.
