From abstract: Drilling at the Project GNOME site, which is in the approximate center of sec. 34, T. 23 S., R. 30 E., NMPM, was undertaken in August and September 1958 by the W-W Drilling Company. The purpose of drilling this hole, which is at the precise location of the proposed shaft, was to determine (1) the lithologic and water-bearing characteristics of the rocks of Cenozoic, Mesozoic, and Paleozoic age that lie above the salt-bearing sequence in the Salado formation; (2) the depth to the top of the unleached salt and associated evaporites in the Salado formation; and (3) the local details of the salt-bearing sequence in the Salado formation.
