Name Origin

The Witt Coal Member of the Bond Formation (Gluskoter, in Kosanke et al., 1960, p. 43) is named for Witt, Montgomery County.

Type Section

The type section consists of exposures along the East Fork of Shoal Creek, about 6.5 miles south of Witt (NE NW SE 7, 8N-2W).


It has been tentatively correlated with a persistent, unnamed, thin coal that occurs about 35 feet above the Reel Limestone throughout eastern and southeastern Illinois.

Extent and Thickness

The Witt Coal is generally less than 1 foot thick and is recognized only in southwestern Illinois.

Stratigraphic Position

In the Witt type area the coal lies approximately 45 feet above the Flat Creek Coal.
