Description

A structural high with an irregular outline was mapped by Bell et al. (1931), who based their interpretations on surface and subsurface data on the Herrin Coal Member. A small area of closure was indicated in Section 34, T5S, R4W. The shape of the feature suggests that it is a product of differential compaction. It does not fit the definition of an anticline and is too insignificant to merit naming as a dome. Moreover, data on the Beech Creek ("Barlow") Limestone (ISGS open files) do not indicate a dome or anticline in this area. The name Jamestown Anticline should no longer be used.
