Vernon, Assistant Director, Florida Geological Survey, assisted the writers many times in the field investigation and offered many helpful suggestions during the preparation of this report. Staff members of the Florida Geological Survey offered assistance and advice during the course of the study. Special recognition is given to Mrs. Ruth Shuler and Miss Betty Youngblocd for the time they spent typing and editing the report. Assistance was given by Mr. Kenneth Highsmith who helped in the preparation of the illustrations and maps. Appreciation is expressed to the staff of the Resident Engineer's office, U. S. Army Corps of Engineers, Chattahoochee, Florida, for making available maps and elevations of the Jim Woodruff reservoir area. Citizens of Jackson and Gadsden counties, Florida, and Seminole and Decatur counties, Georgia, were very cooperative and helpful. 5 I Part I GEOLOGY OF THE AREA IN AND AROUND THE JIM WOODRUFF RESERVOIR INTRODUCTION PURPOSE AND SCOPE OF STUDY In December 1953 Vernon, Hendry, and Yon' made a study of the outcropping Tertiary sediments along the lower portions of the Chatta- hoochee and Flint rivers in the area of the Jim Woodruff reservoir. This investigation was conducted prior to the conclusion of the Jim Woodruff Dam project. The completion of this dam has created a 37,000-acre lake which has masked from future investigations much of those sediments that were previously exposed in the area. This study along the rivers brought to light inconsistencies in the present concept of the geology of this area and the writers thought it wise to undertake a more thorough investigation of the surface geology. The data collected through the study of surface exposures were supplemented by examination of cuttings from three oil test wells and six water supply wells that were drilled in the area and samples
