Observations of sorted patterned ground features, High Valley/Tangle Lakes region, central Alaska, USA
Zeitschrift fur Geomorphologie, Supplementband
Sorted patterned ground forms are common features of the periglacial environment in the High Valley/Tangle Lakes region of Alaska. They are best developed in depressions in hummocky silty tills of Wisconsinan age. Using repetitive photography and surveys of wooden dowels, metal rods, and marked stones, sorted stone circles at six sites were monitored from 1982 to 1987 to determine their degree of activity. Patterns in depressions subject to temporary ponding showed the greatest activity. -from Author
