44 THE COASTAL PLAIN OF NORTH CAROLINA.

streams, and, second, such terrestrial deposits as dunes and humus. In
short, all deposits which are being formed at the present time under
water or on the land by natural agencies belong to this division of
geological time. All of these Recent deposits are being formed in
various portions of the North Carolina Coastal Plain and collectively
afford an ever increasing volume of deposits that represent the influence
of the forces now active.

The boundaries of the Atlantic Coastal Plain are defined with considera-
ble accuracy, the strata constituting it being referred to the “Alluvial
formation.” The author states that it contains beds of shells.

The origin of the deposits of the Coastal Plain is attributed to a mighty
flood of waters which Swept across the North American continent from
the northeast to the southwest. The currents transported the materials

from the interior of the continent and deposited them in their pre
of th L present
position in the Coastal Plain region.
