This map is one of 18 produced for the final open-file report: An Investigation of Potential Geothermal Energy Sources in Mississippi, DoE Contract No. EG-77-S-05-5361; Edwin E. Luper, Principal Investigator; Mississippi Geological, Economic and Topographical Survey; Jackson, Mississippi; 1978. Maps produced include areas of central and southern Mississippi, including all or portions of Adams, Amite, Attala, Calhoun, Carroll, Claiborne, Clarke, Copiah, Covington, Forrest, Franklin, George, Greene, Hancock, Harrison, Hinds, Holmes, Humphreys, Issaquena, Jackson, Jasper, Jefferson, Jefferson Davis, Jones, Lamar, Lauderdale, Lawrence, Leake, Leflore, Lincoln, Madison, Marion, Newton, Pearl River, Perry, Pike, Rankin, Scott, Sharkey, Simpson, Smith, Stone, Sunflower, Walthall, Warren, Washington, Wayne, Wilkinson, and Yazoo Counties. Each map is contoured along a single isothermal surface: Maps 1-A through 1-E: 158F (70C) Maps 2-A through 2-E: 212F (100C) Maps 3-A through 3-E: 248F (120C) Map 4: 302F (150C) Map 5: 356F (180C) Finally, a location map of the 401F (205C) isotherm well is labeled Map 6. Maps 1, 2 and 3 were constructed at approximate scale of 1:250,000. These were broken into 5 sections each. The remaining maps were constructed at approximate scale of 1:500,000. These maps were contoured manually by the staff of the MGS in 1978. Many of the reference marks appear to be incorrectly drawn, so a best-fit methodology was used on the scanned maps to attempt to place them in their appropriate relative location in georeferencing.
