Abstract

In this research the glaciers and glaciated areas of northwest of Bolkar mountains and their geographical conditions have been studied. Recent debris-covered glaciers have been determined in the higher (>2900 m) parts of north and, partially, northeast-facing cirques of two glaciated areas of Pleistocene. The surface area of the largest glacier (Medetsiz) of seven glaciers in Karagöl and Alişan Glaciated Areas is 0,23 km2. On the other hand, Eğerkaya East Glacier occupies a confined place of 0,09 km2. While all the glaciers display the evidence of glacial karst, the Kopukgöl Glacier has exceptionally three supraglacial lakes. In the light of previous data, it is concluded there have been no notable regression in the terminal of the glaciers that since last 60 years. Due to the presence of a debris cover over the glaciers that hampers supraglacially melting, it is possible to suggest that englacial and subglacial ablation should be accounted for of the ablation of glaciers.
