Paint Creek Group (S. Weller, 1913, p. 120; Swann, 1963, p. 76).
Named for Paint Creek, a stream in Randolph County.
The type section of the Paint Creek Group is along a tributary west of McCuen School (E1/2 2, 5S-9W).
The Paint Creek Group is recognized only in western Illinois.
The Paint Creek Group is dominantly shale and limestone and consists of the Downeys Bluff, Bethel, and Ridenhower Formations (fig. M-25). Although the Bethel is normally a sandstone, it is shale in that area and includes a bed of bright red shale. The name was formerly used in southeastern Illinois for the strata now included in the Ridenhower Formation. <center> {| class="wikitable" style="text-align: center;" |- |<gallery caption="" widths=250px heights=250px perrow=4> Figure_M-25.jpg|{{file:Figure_M-25.jpg}} </gallery> |} </center>
