It is about 30 feet thick, but it ranges from about 25 feet in the north to nearly 50 feet in the south.


The Goreville is a resistant and relatively uniform, massive limestone. Most of the limestone is brownish gray but some of it is light gray or gray. It is very fine grained but includes coarse fossil grains, mostly crinoidal fragments. It is cherty to slightly cherty nearly everywhere.
