"One is impressed with the beds above the cement horizon as being decidedly sun cracked. Every layer in a thickness of about 20 feet, along the rails on it, there are at times shown no foot sheets of just square are sun cracked. The bedding is far distinct to be of a continental nature and for the sun cracking indicates great sand flats referred to the sun. Flooded rivers and wind blown sea flooding must account for these accumulations. While we saw no marine life yet at Cumberland we find here an abundance of Ostracoda. The Red beds with their peculiar vertical green markings are the basal series before the cement beds and the mud beds with some crocs on land down. Later the sea deepens and the great coleorans series of Pints and the Sherdubays are laid down. Red beds for 12 feet.
