Fig. 10.—Diagram of the Guanica district The essential feature to be noted is the relation of the Tertiary coastal plain to the oldland rocks and the fact that the oldland upon which the coastal plain was deposited was a very hilly region. Two coastal-plain cuestas are distinctly shown. The inner lowland has been drowned to form Guanica harbor and the ends of the outer lowland have likewise been submerged, forming Salinas Cove and Pardas Hay. Occasional remnants of the coastal plain are to be found in the oldland region, notably near Guanica Central and south of Yauco The point A on the diagram marks the position from which Fig. 11 was taken.
