DISTRIBUTION I AVAILABILITY STATEMENT 12b. DISTRIBUTION CODE 13. ABSTRACT (Maximum 200 words) The Fort Polk region is underlain by Cenozoic terrigenous sediment comprising mostly the Oligocene Catahoula Formation, six formation-rank subunits of the Fleming (Miocene), and Holocene alluvium. Pliocene and Quaternary surface-stratigraphic units incise older units. These surface Cenozoic strata show gentle, homoclinal dip toward the Gulf of Mexico basin and record deposition transitional between continental and shallow-marine, but are dominantly progradational and increasingly terrestrial upsection. The Miocene units comprise alternating coarser-grained, tluvial-dominated lithofacies and fmer-grained, more marine-influenced lithofacies. Gentle dips, semiconsolidated sediment, thick soils, and vegetation generally do not permit direct recognition of surface structure. Drainage lineaments, though suggestive of joint control of drainage, show no clear relation to strikes of measured systematic joints . The primary nonfuel mineral commodity of economic significance, aside from ground water, is gravel. Gravel occurs primarily in the upper Willis, assigned here to the upper Pliocene. Younger Quaternary units have varying but lesser potential for gravel. Flooding is the sole geologic hazard. Flood-hazard potential was compiled from Federal Emergency Management Agency data and modified based on flood-plain topography. Landslide potential, inferred from steepest slopes and clayey substrates, is insufficient to constitute a hazard. 14. SUBJECT TERMS 15.

INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image.

Three refuges -- Breton, Horn, and Petit Bois -- are included in the Gulf Island Refuge complex. Breton was established as the second National Wildlife Ref- uge in 1904. Petit Bois and Horn were added in 1913 and 1958 respec- tively. These island refuges play an important part in the national wildlife conservation effort. During the summer months many thousands of shorebirds, gulls, and terns nest on the sandy beaches and interior areas of the islands. In the winter, waterfowl rest and feed in bays and sounds bordering the islands as well as in the fresh and brackish interior ponds on some of the islands. The refuges range in size from 749 acres on Petit Bois Island to 9,047 acres on the Breton Refuge. Horn Island Refuge contains 2,442 acres. The Chandeleur Islands, which are 35 miles long and average less than a half mile in width, make up the greater part of Breton Refuge.

He accompanied me on several extensive field trips to appraise geomorphic and lithologic evidence and evaluate proposed study approaches. He encouraged academic exposure that helped screen tools useful in quantitative and qualitative evaluation of data and was a steady guide on soil chemistry evaluations. I am indebted to several workers for their interdisciplinary inter­ est and assistance. Dr. Charles Mankin, Director of Oklahoma Geological Survey, assisted with the problem evaluation and made Dr. Arthur Myers and Dr. Kenneth Johnson available for field reconnaissance and bedrock sample identification, respectively. Dr. John Stone, Head, and Dr. John Shelton of the OSU Geology Department shared a field trip to relate to geology-soil-plant association patterns and to advise on preferred bed­ rock samples. Dr. Shelton also assisted with sedimentology evaluations and provided valuable critiques of thesis drafts as a member of the advisory committee.
