|Comments||Surfaces are highly dissected and less continuous than lower terraces. Composed of terraces fomerly designated as Williana, Citronelle, and the highest Bentley. Where overlain by loess, this unit has a red dotted overlay pattern on the source map. Polygons for this unit in our coverage which should have the loess overlay pattern are designated by "-l" being added to the base map unit symbol.|
