Immediately to the east is a high range of
mountains showing at the tip extensive cliffs. This
is probably the same conglomerate seen at Big Stone
Cup and represents the base of the Upper Carbon.
Between this ridge and the railroad lies the entire
Lower Cambrian, Devonian, and Silurian seen. The
ridge to the east has the Clinton and Lorraine.
The rocks in the eastern cliff are seen to dip
to the east.
Back again to the iron mines it seems the rail
road is on the apex of a Heldebyrian anticline and that
it is about 1000 feet to the iron layer. In this distance
then lies the shale and a portion of the Rockwood.
The dip of the surface shale, is here slight and to
the E. The sandstone toward the top of the shale is
in heavy beds and appear to be in some separating
shale. This upper member may be 25 or more
feet thick. The Chattanooga is seen to rest upon
it but a short distance away.
