Abstract

Six measurements of surface-boulder weathering and seven measures of moraine morphometrics were taken at 57 sites in the Kigluaik Mountains, Alaska, to test the morphostratigraphic division of five Quaternary glacial units, to test a threefold subdivision of the late Pleistocene glacial unit, and to estimate the timing of glacial advances. Group means from 70% of the relative-age measures exhibit a positive relationship with relative age of the glacial units. The measures most effective at differentiating between moraine groups were: boulder frequency, tall-boulder frequency, boulder height, distal slope, and boulder angularity. Results of discriminant analysis indicate that moraine-morphometric measures provided slightly better classification results than those of boulder weathering. -from Authors
