plain is separated from the Wicomico plain by a well-defined scarp.
The terrace plains are all more or less dissected by streams.
Geology.—The Patuxent formation, consisting of arkosie sands and
drab, compact clays, is believed to underlie a strip a few miles wide in
the extreme northwest. It passes to the southeast unconformably be-
neath the Black Creek formation. The beds of the latter formation,
consisting of laminated, lignitic sands and clays with interbedded, ma-
rine beds in the upper part, underlie the remainder of the county.
Pleistocene sandy clays, sands, and gravels form a surficial covering
over all older formations. They are referred to the Coharie, Sun-
derland, Wicomico, and Chowan formations. Kerr has mapped both
