Summary:

Named Stormville conglomerate for occurrence near Stormville, Monroe Co., PA. Consists of a calcareous-siliceous fossiliferous bed containing many quartz pebbles. Unit is 15 ft thick. Underlies Stormville shales and overlies Stormville limestone, all included in lower Helderberg. The Stormville is considered of Early Devonian age.

Summary:

Sandstone and conglomerate of the Peters Valley and Stormville Members of the Coeymans Formation thicken from Godfrey Ridge to Cherry Ridge at Bossardville, PA, where they are tongues extending northeastward and are the dominant lithic type of the Coeymans. The Stormville, the thicker of the two members, is raised in rank to Formation from Bossardville southward. In easternmost PA and NJ, the Stormville and Coeymans form a facies mosaic of four interfingering members of the Coeymans: (ascending) the Depue Limestone, Peters Valley, Shawnee Island, and Stormville Members.
