==Name Origin==<br />
The Summum (No. 4) Coal Member of the Carbondale Formation (Wanless, 1931a, p. 182, 192) is named for Summum, Fulton County. The term "No. 4" was first used by Lesquereux (1866, p. 213) for this coal near Shawneetown, Gallatin County. It was also applied incorrectly by Worthen (1870) to the Springfield (No. 5) Coal in parts of Fulton County.<br />
==Type Section==<br />
Summum is near the type locality (NE 3, 3N-2E) (Wanless, 1956, p. 10; 1957, p. 204).<br />
==Correlation==<br />
It is correlated with the Mulky coal of Missouri and Kansas, the Houchin Creek Coal Member (IVa) in Indiana, and the No. 8b coal in western Kentucky.<br />
==Extent and Thickness==<br />
The coal, or the recognized position of the coal, is one of the most widespread stratigraphic markers in the state, but it is generally thin.<br />
==Stratigraphic Position==<br />
It normally is overlain by the black Excello Shale and overlies an underclay.<br />
==Description==<br />
The Summum Coal Member has been mined only locally in Grundy, Kankakee, Fulton, and Saline Counties.<br />
