Description

J. Weller and Bell (1936), working with outcrops of upper Pennsylvanian strata, mapped a large anticline near the village of Omega. Siever's (1950) structure map of the Herrin Coal Member and current maps of the Beech Creek ("Barlow") Limestone (ISGS open files) show no anticline, but only an irregular dip from the southeast. J. Weller and Bell may have miscorrelated their marker beds and misinterpreted the structure. Upper Pennsylvanian stratigraphy of Illinois has been revised several times since 1936 (Weibel 1986). Usage of the name Omega Anticline should be abandoned.
