Large glaciers descended western valleys of the Olympic Mountains six times during the last (Wisconsin) glaciation, terminating in the Pacific coastal lowlands. The glaciers constructed extensive landforms and thick stratigraphic sequences, which
commonly contain wood and other organic detritus. The organic material, coupled with stratigraphic data, provides a detailed radiocarbon chronology of late Pleistocene ice-margin fluctuations. The timing of glacier advances suggests causal links with North
Buried, sand-filled soil wedges exposed in stratigraphic sections at 2 sites near Flagstaff, are larger than any observed desiccation cracks or fissures in modern surface soils or sediments but they are smaller than typical periglacial sand wedges
temperatures are about 0°C. Stratigraphic relations and relative degree of development of associated soils suggest the wedges in Flagstaff are of late Wisconsin age whereas.

stimulated luminescence, to better constrain the age of the Cutler Dam AF. The luminescence ages are supported by new accelerator mass spectrometry (AMS) C 14 ages and amino acid geochronology on ostracode shells from the same stratigraphic section
The study, which aimed at the reconstruction of the geomorphological evolution of the slopes surrounding the village of Corvara in Badia, has implied the geomorphological, stratigraphic and chronological analysis of lanslide processes, in particular
