Summary:

Abandoned name used in KY and IL largely for rocks of Genevievian and Gasperian age, particularly where they are limestone. It probably included younger rocks elsewhere. Used by Ulrich in 1911 in a table only. It was first clearly defined by him in 1917 for exposures at Monte Sano, Huntsville quad, Madison Co., AL.
