Summary:
Linden Hall and Rodman Formations mapped together because of poor exposures. The Linden Hall is here revised to include the Center [Centre] Hall Member along with the Stover and Oak Hall Members. The Rodman and the Linden Hall extend throughout the Valley and Ridge province in central PA and have been traced in the subsurface westward under the Appalachian plateau. The Linden Hall consists of interbedded homogeneous, fossiliferous, and "wormy" limestones. The Stover Member, at the base, consists of medium-dark-gray calcisiltite and calcilutite. Fucoids common. The overlying Oak Hall and Center Hall Members are composed of medium- to thick-bedded calcisiltite and minor calcilutite that are medium to medium dark gray, mottled, and homogeneous. Gastropods, crinoid columnals, and thin-shelled brachiopods are common. Combined thickness of the Linden Hall and Rodman along PA Rte 453 is 40+/-3 m. Stover Member is 14+/-2 m; Oak Hall and Center Hall are 20+/-2 m. Linden Hall conformably overlies the Snyder Formation. No basis given for Late Ordovician age assignment.

Summary:
In section C-C' the Linden Hall is called the Linden Hall Limestone in PA based on prevalent limestone lithology. The Linden Hall Limestone, along with the Hatter and Snyder Limestones (all of the Black River Group), correlate with the lower one-half of the Chambersburg Formation in Franklin Co. PA.
