Clay in lower portion conformably transitioning from underlying Demopolis Chalk. Sand, Chalk and limestone above thetransitional clay. Transitional clay is laminated to thin bedded; dark greenish gray, medium gray and reddish tan where highly weathered; locally sandy; and fossiliferous. Sand, chalk and limestone are interbedded lenses of sand, chalky sand, siltychalk or chalky limestone. Sands are tan to red where weathered;fine grained; micaceous; calcareous; and fossiliferous. Chalks are gray to tan; often silty and sandy; and fossiliferous. Limestones are light gray to nearly white where weathered;often sandy; and fossiliferous.Thickness ranges up toapproximately 165 feet.

Approximately 25 feet thickadjacent to larger stream Alluvium or younger terrace deposits,thinning or non-existent up tributiaries. Qt1 - youngest andlowest in elevation of Terrace alluvium deposits. Qt2 - secondyoungest in age and elevation of Terrace alluvium deposits. Qt3 - third youngest in age and elevation of Terrace alluviumdeposits. Qt4 - fourth youngest in age and elevation of Terrace alluvium deposits. Qt5 - fifth youngest in age and elevation of Terrace alluvium deposits. The older in age and higher in elevation Terrace alluvium deposits become increasingly eroded and discontinuous.
