English Abstract: The eastern part of the North Anatolian Mountains is the place where the Pleistocene glaciations is most effective.In these mountains, which have many summits over 3500 meters, especially the high parts above 2500 meters constitute a significant glacial area. Important peaks of the Eastern Black Sea Mountains; Glaciers and glacier shapes on the northern slopes of Kackar, Vercenik, Tatos (Dilek), Goller(Hunut) and Bulut-Altiparmak have been subject to various investigations because of these features. In the Eastern Black Sea Mountains, there are also some glacial traces, glacial shapes, and even current cirque glaciers in the southern-facing parts of these summits. The southern part of the Tatos Mountains, which forms one of the highest peaks of the Eastern Black Sea Mountains, is also where glaciation is effective.The glacier valleys reflecting the traces of the Pleistocene glaciations, the various glacial shapes and glacier lakes together with the northward-facing Catakkaya debris covered glacier, covered entirely with a rubble, detected at the steep slope of a glacial cirque is a significant finding that reveals the impact and significance of glaciation in this area. Turkish Abstract: Kuzey Anadolu Daglari’nin dogu kesimi, Pleistosen buzullasmasinin en etkili oldugu yerlerdendir. 3500 metreyi asan cok sayidaki zirveye sahip olan bu daglarin, ozellikle 2500 metrelerden yuksek kisimlari kayda deger bir buzullasma alani olusturmaktadir. Dogu Karadeniz Daglari’nin yuksek doruklari; Kackar, Vercenik, Tatos (Dilek), Bulut-Altiparmak ve Goller (Hunut) daglarinda, ozellikle kuzeye bakan yamaclarda bulunan buzullar ve buzul topografyasi sahip olduklari niteliklere bagli olarak pek cok arastirmaya konu olmus ve olmaya da devam etmektedir. Kuzey Anadolu Daglari’nin bu yuksek doruklarinin guneye bakan yamaclarinda da dikkat cekici bir buzullasma etkisi, buzul topografyasi, hatta aktuel sirk buzullari gozlenmektedir. Dogu Karadeniz Daglari’nin yuksek zirvelerinden birini olusturan Tatos Dagi’nin (3550) guney kesimi, onemli bir buzullasmanin meydana geldigi yerler arasindadir. Pleistosen’de etkili olan buzullasmanin izlerini yansitan tekne vadiler, buzul golleri ve cesitli buzul sekilleri ile birlikte bu alanda kuzeye bakan, dik yamacli bir glasyal sirk icinde belirlenen ve tamamen bir enkaz ortusuyle kapli olan Catakkaya dokuntu ortulu buzulu, bu alandaki buzullasmanin etki ve onemini ortaya koyan kayda deger bir bulgu olusturmaktadir.
