"This transition series is about 200 foot thick and consists of about 6 zones of Mauch Chunk like red shales separated by beds of sandstones or conglomerate like those of the Pittsville. Hunger says that in as yet no final evidence to indicate that this transitional series is Mauch Chunk in Pittsville, Below the Mauch Chunk is the fairly uniform series over 3000 feet thick of red shales and interbedded sandstones. The latter often have drifted plant stems and in the muddier sandstones roots in place or fossils that are known from these sandstones. The red shales present much evidence of continental deposition. They are at times riffled, always have evidence of plant material and roots, are usually sun cracked and often the thin dried pools of curled mud have been squeezed together into an intraformational mud
