Stratigraphic relationships

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.

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).





Well log characteristics


Age and correlation

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.
