The dataset pp1773_unit_alt_grid shapefile represents the altitude of aquifer and confining unit surfaces of the Atlantic Coastal Plain of North and South Carolina described in Professional Paper 1773. The three-dimensional hydrogeologic framework was determined from borehole geophysical logs and well-to-well correlations. Detailed stratigraphic data from coreholes and drill cuttings were collected to assist with correlations, although the primary concern was the continuity of hydraulically connected permeable and less permeable strata through the Coastal Plain. Quaternary through Cretaceous sedimentary sections were separated into component hydrogeologic units, mapped, and described across the study area using groundwater levels, borehole geophysical logs, paleontologic data, borehole lithologic logs, chloride concentrations, aquifer-test data, and surface resistivity measurements.
