Summary:

Pg. 262. Herrin limestone in McLeansboro formation. The limestone cap rock of Herrin No. 6 coal, which I shall call the Herrin limestone, since it is so commonly associated with Herrin coal, is an impure, earthy dark-gray, dirty-looking limestone that breaks with splintery fracture. Where exposed along streams it spalls off in angular fragments showing little structure. Contains fossils. Age is Pennsylvanian.
Present in Saline Co., southern IL.
