Name Origin

The Reel Limestone Member of the Bond Formation (Worthen, 1875, p. 55) is named for Reel's Corner, Wabash County, (NE? 8, 1S-12W).

Extent and Thickness

The Reel Limestone occurs in eastern and southeastern Illinois, and is 1-3 feet thick.

Stratigraphic Position

The Reel Limestone is the first limestone above the Shoal Creek Limestone and lies 85-100 feet above it. It is generally underlain by a thin, black fissile shale that directly overlies the Flannigan Coal.


The Reel Limestone is dark gray.


The Reel Limestone contains many small gastropods, pelecypods, brachiopods, and incrusting Foraminifera.
