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.
