Glacial landforms in the southwestern part of the Anatolian Peninsula are found at lower elevations than the rest, suggesting that glaciers were present during the Late Pleistocene. Karadağ, located west of the Western Taurus Mountains, provides evidence of the climatic conditions that facilitated this extensive glaciation. It is characterized by numerous peaks exceeding 2300 m above sea level (asl), with the highest peak reaching 2418 m, making it the region's largest glaciation area. This high mountain mass is composed mainly of limestone and dolomite. This study focuses on the glacial landforms in Karadağ to reconstruct the Late Pleistocene glacial chronology and palaeoclimate of the Western Taurus Mountains. We employed detailed UAV photogrammetry, extensive fieldwork and mapping, surface exposure dating with cosmogenic 36Cl, meteorological measurements, palaeoglacier reconstruction, and palaeo-equilibrium line altitude (pELA) calculations. Karadağ, a topographic barrier to humid air masses from the Mediterranean Sea, ranks as the second wettest area in the Western Taurus Mountains. At a meteorological station we installed in Karadağ, an annual precipitation of 1700 mm or more was recorded, highlighting its significant precipitation. In Karadağ, we have identified two glacial valleys with a maximum length of 4.5 km and six cirques. The glaciers reached their maximum extent around 22.4 ± 2.8 ka during the Last Glacial Maximum (LGM), facilitated by the lowering of the pELA to 2090 m. During the LGM, the glaciers covered an area of approximately 3.5 km2 and reached a maximum thickness of about 140 m. Sample TRKR 10 at 2015 m probably belongs to the LGM period. Although a single sample does not conclude definitive conclusions, the presence of the moraine at its highest position indicates the maximum thickness of the glacier. Following the LGM, two more significant glacier advances occurred during the Lateglacial (15.5 ± 2.7 ka) and the Younger Dryas (12.4 ± 1.1 ka). During the late Pleistocene glaciations, and especially during the LGM, Karadağ probably received more precipitation than today, leading to the formation of glaciers at relatively lower elevations than on the Anatolian Peninsula.

Bayrakdar, Cihan; Çilgin, Zeynel; Saris, Faize
Karadag is one of the mountains subjected to the Pleistocene glaciations in the Teke Peninsula (Western Taurus) along with Beydaglari, Akdag, and Sandiras Mountains. Karadag, which reaches 2418 m summit at a 30 km straight distance from the northeast of Fethiye Bay, has many peaks over 2300 m. There are plenty of glacial researches and dating studies aim to reveal Pleistocene glaciation chronology of the mountains such as Sandiras and Akdag in the Teke Peninsula. On the other hand, glaciations in Beydaglari were mentioned superficially and in general terms. Lastly, there has not been known any glaciation phenomenon in Karadag, in other words there are not any studies concerning the glaciation on the mountain. However, Karadag has distinctive cirques and moraines on the slopes of high elevations near the peak. In this study, we identified glacial valleys, cirques developed in different sizes and aspects and lastly frontal and hummocky moraines in front of these cirques. They are descending to the elevation of 1800 m. With this study, a new glacial area was identified in Turkey and made a contribution to the glaciation inventory of Turkey. This study aims to reveal the geomorphological and climatological characteristics of this area with regard to tectonic, climatic and karstic characteristics during Pleistocene. Maps and relevant outputs were created and analyzed by geographic information systems using the spatial data obtained from the field studies, unmanned aerial vehicles and meteorological stations.
