An oldest dryas glacier expansion on mount pelister (former Yugoslavian Republic of Macedonia) according to10Be cosmogenic dating
We provide a geomorphological analysis of a glacial valley on Mount Pelister, in Macedonia. Three boulders from a frontal moraine were dated with the cosmogenic nuclide isotope 10Be. The results demonstrate that the boulders have been exposed since 15.24 ± 0.85 ka. This age constrains the formatio...
