METHOD FOR RECOGNIZING LOCAL BEDROCK INFLUENCE ON DRIFT PLAINS

摘要: Analysis of topographic and bedrock surface data from 41 sites 23.3 km2 (9 m2) within Midwestern areas glaciated during the Late Wisconsinan identifies an average drift thickness-maximum relief transition equation for presence or absence influences on detail. For with thicknesses between 15 35 m, occurs when exceed 0.5 maximum + 10 m. This may provide a practical tool in searching buried valleys.
