Secretary LETTER OF TRANSMITTAL Office of the Mississippi Geological Survey University, Mississippi, March 15, 1954 To His Excellency, Governor Hugh L. White, Chairman, and Members of the Geological Commission Gentlemen: Geology of Marshall County Sand, sand, sand everywhere, and not one grain to know. Sand, sand, sand everywhere, and not one bed to place. Trite, yes; but so true, so applicable, so completely summarizing. "Stratigraphic relationships in northern Mississippi have passed, and probably will continue to pass, complete understanding." So says the author, climaxing seventy years of geologic studies of the "sand problem" by various workers. And yet the author "believes that he has identified the major stratigraphic units which crop out in Marshall County, and has found a suf ficient number of points on their contacts to enable him to delimit the units geographically and stratigraphically, at least in a general way." And so at last the foundations are laid for the conclusions he so cautiously presents in the report. It has been a tough assignment — an assignment so challenging that the State Geologist craved it for his own, but other matters consumed his time. Perhaps the discovered "points on their contacts" will enable the "surface oil geologist" to determine favorable oil structures deep beneath the sands. At least they point up the region where geophysical crews should begin their more expensive exploration. Naturally the State Geologist hopes his forecasts of 20 years ago, that deeply sand-buried structures would probably yield oil, will prove correct. In fact they have been found to contain gas and distillate, but the "tight-sand reservoirs" have, for the most part, yielded up the hydro carbons too slowly to be economically profitable. Yet Carter Oil Com pany technologists with the "know-how" have fractured the reservoirs in northeastern Mississippi to the extent of making them productive. The report, Geology of Marshall County by Franklin Earl Vestal, to be printed as Bulletin 78.

Marshall County geologic map „ Back MARSHALL COUNTY GEOLOGY FRANKLIN EARL VESTAL, M.S. INTRODUCTION Marshall County, an area of 689 square miles,1 is the western most, except for DeSoto, of the six Mississippi counties which border Tennessee (Figure 1). It is bounded on the east by Benton and Union Counties, on the south by Lafayette, and on the west by Tate and DeSoto. Roughly, the county lies within a quadri- Figure 1.—Location of Marshall County. lateral formed by the parallels of 34°30' and 35° north latitude, and the meridians of 89° 15' and 89°45' west longitude.2 Its maxi mum east-west straight-line length is 27 miles, and its greatest north-south extent is 34 miles. All boundary lines are straight with the exception of the eastern half of the southern boundary- line, which is the Tallahatchie River. The boundary-line on the east is offset in two places, so that in the southeastern corner of the county it is 6 miles east of its position in the northeastern corner. The western boundary-line also is offset in such a way 8 MISSISSIPPI STATE GEOLOGICAL SURVEY that its southernmost 9-mile segment is 3 miles farther east than the 21-mile segment of the remainder (Plate 1). The locations of the boundary-lines, giving the county such an irregular shape, resulted from changes during its history. According to Rowland," Marshall County, named for Chief Justice John Marshall, was established February 9, 1836, and formerly included territory which has since been apportioned among Benton, Tate, and other counties. Originally it comprised about 23 townships, 828 square miles. "In 1870 it gave up part of its territory on the east to Benton County, and in 1873 it gave up another portion of its area to assist in the formation of Tate County, and received in lieu of the portion surrendered to Tate, all that portion of DeSoto County lying within Townships 1 and 2, Range 5 West. Subsequent slight modifications of its bound aries have resulted in reducing its area to 689 square miles." The population of Marshall County on April 1, 1950, was 25,106, fewer by 416 than the 1940 population of 25,522. In con trast to the 1.6 percent loss of population for the county as a whole, the population of Holly Springs, the county seat, increased from 2,750 in 1940 to 3,276 in 1950 — a gain of 526 people, or more than 19 percent, in the decade.4 Except for the people of Holly Springs, the population of Marshall County is entirely rural, by the definitions of "urban" and "rural" adopted by the U. S. De partment of Commerce Bureau of the Census for the 1950 census, according to which population is classed as urban only where it lives in groups of 2,500 or more/' The rural population is fairly evenly distributed over the county. Holly Springs is the largest town, Byhalia is second in pop ulation, and Potts Camp third." Other towns and villages of the county are: Mount Pleasant, Slayden, Hudsonville, Victoria, Red Banks, Waterford, Chulahoma, Cornersville, Warsaw, and Wat son.
