Historical:Pond Creek Coal Member
M. E. Hopkins and J. A. Simon
The Pond Creek Coal Member (Kosanke et al., 1960, p. 37) is named for Pond Creek in Williamson County.
The type section of the Pond Creek Coal is at a depth of 125 feet in Consolidated Coal Company drill hole 91 (SW NE NE 21, 8S-3E).
It previously was informally called the Second Cutler Rider coal.
It may be equivalent to the Rock Branch Coal of southwestern Illinois.
Extent and Thickness
The Pond Creek is more extensive than either the De Graff Coal or the Lake Creek Coal, which, respectively, lie just a few feet above and below the Pond Creek, but the Pond Creek is recognized only in southern Illinois.
