The Mississippian Pocono Formation is a mapped bedrock unit in Pennsylvania, Maryland, and West Virginia, in the United States. It is also known as the Pocono Group in Maryland and West Virginia,[2] and the upper part of the Pocono Formation is sometimes called the Burgoon Formation or Burgoon Sandstone in Pennsylvania.[3][4] The Pocono is a major ridge-former In the Ridge-and-Valley Appalachians of the eastern United States[5]
The Pocono is also a lateral equivalent of the Purslane Sandstone in Maryland and West Virginia. D. Brezinski of Maryland Geological Survey recommended abandoning use of the term Pocono in Maryland in favor of "Purslane" in 1989.[6]
The major ridge makers are the Tuscarora (T), Pocono (Po), and Pottsville (Pt) Formations.
