The Ohio Geological Survey's Mobile B-61 Pacemaker core rig drilling in Raccoon Township, Gallia County, Ohio, for a Clarion (No. 4a) coal study. The image was taken in by Michael C. Hansen in 1982 based on information from Ohio Geological Survey Core Record File No. 2541.
REVIEW
Double check exact location of core #2541.
For information about the Ohio Geological Survey's drill rigs, see: Survey Begins Coring Program with New Rig by Michael C. Hansen (Ohio Geological Survey, Ohio Geology Newsletter, Fall 1981) page 1. In May 1981 the Survey...received its...truck-mounted coring rig...a custom-built B-61 Pacemaker manufactured by Mobile Drilling Company, Inc., of Indianapolis, Indiana has a maximum coring depth of nearly 3,000 feet....Survey geologist David A. Hodges is in charge of the coring rig...Driller is Michael J. Mitchell and John L. Sullivan is assistant driller. In addition to this crew, assigned full-time to the rig, a project geologist is in charge of sitting holes and logging core for each particular study.

AND Horace R. Collins-10th State Geologist by Robert G. Van Horn (Ohio Geological Survey, Ohio Geology Newsletter, Summer 1988) page 2, column 2, paragraph 3:
...purchase the Survey's first core-drilling rig, a Mobile B-61 Pacemaker, in 1980. A drilling crew was assembled, and drilling began in May 1981. This program proved to be so successful that...two other drill rigs (were purchased) in 1986--a Longyear Hydro 44 which is capable of core drilling to a depth of almost 6,000 feet, and a CME auger rig which is capable of obtaining continuous, oriented core samples of unconsolidated sediment. In addition to the purchase of these other rigs, the Division's drilling program had gained sufficient appreciation from Ohio mineral industries that one company, France Stone Company, donated a fourth core-drilling rig to the Survey.
