Name Origin

The Pope Creek Coal Member of the Abbott Formation (Wanless, 1931a, p. 189-190, 192) is named for Pope Creek in Mercer County.

Type Section

The type locality is along Pope Creek (cen. 33, 14N-2W) (Wanless, 1929, p. 52; 1956, p. 9).


The Pope Creek has been correlated with the Delwood Coal of southern Illinois, the Upper Block Coal Member of Indiana, and the No. 3 (Ice House) coal of western Kentucky.

Extent and Thickness

The Pope Creek Coal is widespread in the western Illinois outcrop belt, where it is as much as 3 feet thick and averages about 1 foot (Wanless, 1957).

Stratigraphic Position

The upper part of the coal is truncated in places by the Bernadotte Sandstone, but more commonly the coal is overlain by a gray shale several feet thick.
