Radiocarbon dating showed the age of the soil was 12,650 cal years before present, which coincides with the beginning of the Younger Dryas cold period (YD). This result indicates that the ice cap did not exist in the Bølling-Allerød period (BA), which is the warm period before the YD, and that climate of BA was significantly warmer than present. It also indicates that the ice cap has never disappeared in any warm periods in Holocene, such as Hypsithermal and Medival warm period. \r\n\r\n","author":null,"citation":"Takeuchi, N.,  K.
