Summary:
Skaneateles Shale of Hamilton Group extended from southwestern NY, western PA, and eastern OH into the subsurface of northern WV and far western MD (Garrett Co.). Unit consists mostly of dark- to medium-gray fossiliferous shale and mudrock. Contains a black shale facies that resembles the Marcellus Shale. Includes the Stafford Limestone Member at its base. The Stafford is thin but extensive and can be traced in the subsurface as far southwest as north-central WV and southeastern OH. The Skaneateles loses its identity to the west where the Hamilton is undivided. Grades into the Plum Brook Shale of northern OH or the lower part of the Olentangy Shale.
