Description

A large anticline with a curved axis was mapped by J. Weller and Bell (1936) on the basis of outcrops of upper Pennsylvanian rocks. No such anticline appears on maps of deeper horizons, including the Herrin Coal (Siever 1950), Beech Creek ("Barlow") Limestone, or Karnak Limestone Member (ISGS open files). Beech Creek and Karnak structure maps show slight southward nosing of contour lines in the area where Weller and Bell mapped the western part of the Louisville Anticline. This nosing is interpreted as representing the southward termination of the Iola Anticline; therefore, the name Louisville Anticline should be dropped.
