What Caused the Younger Dryas Cold Event? - GeoScienceWorld The Younger Dryas Glacial Map is an interactive map which reconstructs the extent of the glaciers formed in Scotland and northern England during the Younger Dryas. The analysis of Greenland Summit ice cores, as part of the Greenland Ice Sheet Project2 and Greenland Icecore Project, estimated that the Younger Dryas started about 12,800ice (calibrated) yearsBP. Climatic change in the central Andes during the DCR, however, was significant and was characterized by a shift to much wetter and likely colder conditions.
