DEM of Wetumpka, north is to the top. Compiled by Dr. Kevin Evans, Southwest Missouri State University.
Left: Location of the Wetumpka structure (dot) in Alabama. Major geological provinces are indicated. Right: Generalized geological map of Wetumpka structure showing main terrains (discussed in text) and adjacent geology. Crystalline-rim terrain (crt); intra-structure terrain (ist); extra-structure terrain (est); Upper Cretaceous undeformed units (Ku); pre-Cretaceous crystalline units unaffected by Wetumpka structure (pK). Faults are tick-marked on down side. Star (*) marks drilling location for two wells. From King et al. (2002).
This is a painting by space artist Jerry Armstrong of Atlanta, Georgia, showing Wetumpka impact crater during Late Cretaceous a few months to years after impact.
