Digital hydrogeologic surface of the Lower Claiborne aquifer in Alabama, Arkansas, Louisiana,
and Mississippi. The hydrogeologic unit dataset contains 414 rows and 394 columns
representing 1-mile grid spacing. In general, limitations of data interpolation included areas of
sparse geophysical log control points, log datums not clearly defined for some logs, unknown
exact extent of each hydrogeologic unit in subcrop, interpolation limitations, and values
averaged over 1-mile grid spacing.
