In Wabash County the part of the Teays Valley above the ‘deep stage’ consists of broad terraces at an altitude of about . From this terrace level the bedrock rises gradually to the on the Lexington pene-plain surface. These terraces probably correspond in age to an erosional surface in the unglaciated areas known as the Parker strath, which was the result an erosion cycle that ended before the Kansan phase of the pre-Illinoian glaciation. More recent correlation places its age as pre-Nebraskan. The Parker strath probably represents an erosional level existent at the beginning of the Pleistocene before the rejuvenation associated with, and following, the Nebraskan glaciation. The general appearance and width of the strath terrace along the Teays Valley in Indiana indicates that it represents only a slight rejuvenation following the Lexington cycle.
