General Description

Drill hole data for this map compiled from: Prior, W. L.; Clardy, B. F.; and Baber, Q.M. III, 1985, Arkansas Lignite Investigations, Information Circular 28-C Arkansas Geological Commission, 214 p.

Approximate locations of Near Surface Lignite Resources or areas of Indicated Reserves were excerpted from unpublished company reports submitted to the Ozark Regional Commission circa 1975-1979.

Note: For the purpose of efficient database management, the drill hole numbers in the Crowley's Ridge study area and alpha-numeric drill hole numbers vary from the original publication, Prior, 1985.

The series of numbers in the Crowley's Ridge area have been changed from 1-116 to 1623-1738. All alpha-numeric drill hole numbers (eg. 78b) were changed to 5000-5021.  Drill holes 1579-1622 were drilled by the Arkansas Geological Commission after publication.

Surface and down-hole information for the drill holes represented on this map are available on CD-ROM in table format as Miscellaneous Map Series 101 part 2 from the Arkansas Geological Commission.
