Summary:

At 823 feet depth in Livonia salt shaft, at Livonia, Livingston Co., NY, occurs 2 feet of compact grayish or chocolate-colored limestone, somewhat bituminous, shaly at top, which is given the name Stafford limestone from its excellent development at Stafford, Genesee Co., NY. Hamilton fossils are very abundant. This unit persists from Livonia eastward probably not less than 50 miles. In the shaft section, as at all its observed outcrops, it bears a Hamilton fauna with a few Marcellus species. The Stafford overlies 28 feet of compact black, very bituminous but not heavy-bedded shales.

Summary:

Stafford Limestone Member of Skaneateles Shale extended from southwestern NY into western PA and into the subsurface in eastern OH, northern WV, and far western MD (Garrett Co.). Marks the base of the Skaneateles and clearly separates it from the underlying Marcellus.
