Evidence for glacial advances in the Anatolian mountains prior to the Last Glacial Cycle (LGC) are unknown. Oldest known glacial advances date back to pre-LGM (Last Glacial Maximum) within the LGC. Glacial landforms and deposits related to the pre-LGM advances are found in the Eastern Black Sea Mountains, Western Taurus Mountains, and Northwestern Anatolia. The state-of-the-art information point toward a threefold glacial advance around the MIS 5d-3. 10Be exposure ages of two granite boulders deposited at the limit of glacial deposits in Mount Uludağ in the Northwestern Anatolia provided the first hint for the presence of pre-LGM glaciations in Anatolia. The Başyayla paleoglacier in the Kaçkar Mountains in the Eastern Black Sea Mountain Range advanced prior to 55 ka, at c. 40 ka, and c. 30 ka before the onset of the LGM expansion. Similarly, well-preserved morainic amphitheater in the Kuruova valley in Mount Akdağ in Western Taurus Mountains bears the evidence for glacial advances at c. 40 and 30 ka. The more extensive glaciers during the LGM, which eroded the existing glacial landforms and deposits, can enlighten the dearth of evidence for the pre-LGM glacial advances in the Anatolian mountains, as well as the poor degree of preservation as a result of rapid tectonic evolution.
