Abstract:
THE TECHNIQUES USED TO INTERPRET GRANULAR MATERIALS FROM AERIAL PHOTOGRAPHS ARE DISCUSSED. THERE IS NO STANDARD AIRPHOTO PATTERN THAT CONTAINS ALL ELEMENTS OF THE GRANULAR PATTERN. THIS IS DUE CHIEFLY TO THE VARIATIONS IN OCCURRENCE AND TO THE VARIATIONS IN DEPTH AND TYPE OF NATURAL OVERBURDEN ON SUCH LAND FORMS. THE VARIOUS LAND FORMS IN WHICH GRANULAR MATERIAL CAN OCCUR ARE KAMES, ESKERS, GLACIAL OUTWASH, TERRACES, LACUSTRINE BEACH RIDGES, RECENT ALLUVIUM, COASTAL PLAINS, AND GREAT PLAINS AND GREAT PLAINS OUTWASH MANTLE. THE VARIOUS ELEMENTS OF THE AIRPHOTO PATTERN NEEDED FOR IDENTIFICATION OF ANY SOIL REGION ARE: COLOR TONE, LAND FORM, GULLY SHAPES, LAND USE, EROSION, VEGETATIVE COVER, AND DRAINAGE PATTERN. THE MORE GENERAL ELEMENTS OF THE GRAVEL PATTERN ARE: ONE OF THE CHARACTERISTIC LAND FORMS ASSOCIATED WITH THE PHYSIOGRAPHY OF THE REGION; LIGHT COLOR TONES; A MOTTLED EFFECT; OCCASIONAL CURRENT SCARS; ORCHARDS; GRAVEL- TYPE GULLIES; AND A GENERAL ABSENCE OF SURFACE DRAINAGE. /AUTHOR/
