"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.
