AT THE OUTSET OF THE CURRENT SOIL MAPPING PROGRAM, FROM AERIAL PHOTOGRAPHS, OF THE STATE OF INDIANA CERTAIN GLACIAL AIRPHOTO PATTERNS WERE FOUND TO BE VERY COMPLEX AND AS A RESULT AN ENDEAVOR WAS MADE TO TRACE THE GLACIAL FEATURES WHICH HAVE COMPLICATED THE PATTERNS. THE FIRST PART OF THE PAPER DISCUSSES THE AREAL SOIL (REGIONAL SOIL) MAPPING PROGRAM AND HOW IT IS BEING DONE FROM AERIAL PHOTOGRAPHS. THE COMMON BEDROCK AND GLACIAL PATTERNS ARE DISCUSSED AND ILLUSTRATED SO THAT THE READER MAY BETTER UNDERSTAND THE COMPLEX PATTERNS. THE REMAINDER OF THE PAPER DISCUSSES MANY OF THE COMPLEX PATTERNS AND THE GLACIAL FEATURES WHICH CAUSE THEM TO BE DEVELOPED. THE COMPLEX PATTERNS OF THESE SOILS ARE BEING STUDIED WITH THE OBJECT OF DETERMINING THE LATERAL EXTENT OF SUCH SOILS AND THEIR RELATION TO HIGHWAY ENGINEERING. THE FOLLOWING ARE A FEW OF THE COMPLEX SITUATIONS BEING STUDIED: INTERMIXED GRAVEL AND DRIFT ON GLACIAL DRIFT OF AN OLDER PERIOD; RECENT TERRACE GRAVELS ON OLDER DRIFT DEPOSITS; SAND CLAY AND GRAVEL CLAY DEPOSITS ASSOCIATED WITH OLDER GLACIAL DRIFT; PRE-GLACIAL DRAINAGE; GLACIAL DRIFT BORDERS; AND RESORTED RECENT DRIFT ON OLDER DRIFT. THIS STUDY REVEALS THAT THESE PATTERNS HAVE DEFINITE ELEMENTS WHICH AID IN THEIR IDENTIFICATION. MATERIALS ASSOCIATED WITH THESE PATTERNS ARE IMPORTANT IN BOTH HIGHWAY AND AIRPORT ENGINEERING. FOR EXAMPLE, SAND-CLAY AND GRAVEL- CLAY MATERIALS FIND USE IN BASE COURSE CONSTRUCTION AND IN THE SURFACING OF COUNTY ROADS IN AREAS WHERE OTHER ENGINEERING SOILS ARE UNDESIRABLE. THE PREDICTION OF OLDER DRIFT IS IMPORTANT BECAUSE OF ITS DENSE, INDURATED STRUCTURE AND LOW PERMEABILITY. THE SOIL MAPPING PROGRAM, WHICH IS BEING INITIATED, IS COMPREHENSIVE AND A LARGE AMOUNT OF DATA ARE NOW BEING OBTAINED. WHEN THE PROJECT IS COMPLETED, MAPS WILL BE AVAILABLE WHICH WILL SHOW THE LOCATIONS OF POTENTIAL SOURCES OF AGGREGATES, BASE COURSE MATERIALS, AND MATERIALS FOR LOW COST ROADS FOR STATE AND COUNTY USE. MAPS WILL BE AVAILABLE FOR USE IN EVALUATING PAVEMENT PERFORMANCE; THEY CAN ALSO BE USED IN THE DESIGN OF PAVEMENTS ON AN AREAL OR REGIONAL BASIS FROM THE STANDPOINT OF SOILS. THE SPEED WITH WHICH THE PROGRAM PROCEEDS WILL DEPEND, LARGELY, UPON THE ACCURACY AND REFINEMENT WITH WHICH THESE COMPLEX GLACIAL FEATURES CAN BE EVALUATED FROM AERIAL PHOTOGRAPHS. /AUTHOR/
