Morphometric analysis of Pleistocene glacial deposits in the Kigluaik Mountains, northwestern Alaska, USA

Morphometric and other relative-age data were collected on early- to late-Pleistocene end moraines located in the Kigluaik Mountains of Seward Peninsula, Alaska. Discriminant analysis indicates that average slope, calculated from the slope-frequency distribution, is the best single distinguishing criterion, and that even a few simple field measurements of morphometry provide a viable basis for subdividing and correlating moraines. Morphometric and other relative-age data constrain the timing of glaciations in the Kigluaik Mountains, and suggest that successively older advances are separated by intervals of increasing duration. -from Authors
