Abstract

In August 2003, the U.S. Geological Survey (USGS), in cooperation with the North Carolina Geological Survey (NCGS) and the Raleigh Water Resources Discipline (WRD), drilled a stratigraphic test hole and well in Bladen County, North Carolina. The Elizabethtown test hole (BL-244/BL-C-1-2003) was cored on the property of Mr. Robert Henry Jessup, Elizabethtown, North Carolina. The drill site is located on the Elizabethtown South 7.5 minute quadradrangle at lat 34°33'06.17"N., long 78°31'33.95"W. (decimal degrees 34.551716 and 78.526096). The altitude of the site is 109.4 ft above mean sea level as determined by a Trimble Global Positioning System (mapping grade). This test hole was continuously cored by Eugene F. Cobbs, III and Casey "Lake" McKinney (USGS) to a total depth of 567.0 ft, and a 2-in. monitoring well was set at a depth of 420 ft below land surface. Upper Cretaceous and Quaternary sediments were recovered from the site. As of publication of this report, the core is stored at the NCGS Coastal Plain core storage facility in Raleigh, N.C.

In this report, we provide the initial lithostratigraphic summary recorded at the drill site, along with site core photographs, data from the geophysical logger, and initial hydrogeologic interpretations. The lithostratigraphy from this core can be compared to previous investigations of the Kure Beach corehole, near Wilmington, NC in New Hanover County, the Esso #1, Esso #2, Mobil #1 and Mobil #2 cores in the Albemarle and Pamlico Sounds, and the Cape Fear River outcrops in Bladen County. This core is the second in a series of planned benchmark coreholes that will be used to elucidate the physical stratigraphy, facies, thickness, and hydrogeology of the Tertiary and Cretaceous Coastal Plain sediments of North Carolina.
