clays and light gray, arkosic sands, are exposed at many places along
the cove sides of the river bends and are in most places overlain by 6
to 10 feet of Pleistocene terrace deposits. Beyond the point indicated
there are no more surface exposures of the Patuxent formation:

Tar River exhibits the beds of the formation from a point about 4
miles below Dunbar Bridge in Edgecombe County to Parker Landing
in Pitt County. Above Tarboro the occurrences are all low, as a rule
less than 6 feet being revealed; while below this town the surface of
the formation gradually rises to a maximum height of 16 or 18 feet
near Penny Hill in Pitt County. (See sketch map of Tar River,
Fig. 7.)

From its first appearance in Edgecombe County to a point about 4
mile above Parker Landing the formation is overlain either by beds
of Miocene age or by Pleistocene terrace deposits. At the last point
indicated, however, and also a short distance below Parker Landing,
the Black Creek formation appears resting unconformably upon the
Patuxent formation. Beyond this the latter does not again appear,
having passed finally from view beneath the water level.
