The fieldwork consisted of excavating stratigraphic exposures (up to 5 meters height) inside the permafrost. These sections were excavated to clarify the depositional sequences that occurred during the Plio-Pleistocene boundary. For stratigraphic exposures, detailed (cm) sedimentological and stratigraphic descriptions were done in order to reconstruct the depositional environments. Boreholes were also drilled with a permafrost core drill to reach deeper strata. This excavation work was combined with large scale stratigraphic characterization of the study site with a differential GPS. The DGPS was also used to geo-reference the bedrock at the study site for a bet...
