Paleogeographic reconstruction and regional setting of Wetumpka target area during early Campanian (81.5 +/- 1.5 Ma). All features and relationships are shown at approximately correct scale, including the impact crater diameter (based upon data and references cited in King, 1994, and King and Skotnicki, 1994). Paleobathymetric contours are dashed line; environments are labeled. Wetumpka impact crater is at the star; Appalachian headland is in northeastern map area.
