Late Quaternary glacial features have been found in the Central Taurid Mountains, in U-shaped valleys located at an altitude of more than 2000 m and surrounded by mountain ranges reaching 2850 m. No present day active glaciers exist in this area where the snowline elevation lies at about 3500 m. The Namaras Valley and its tributary Susam Valley are characterized by coarse loose material forming chaotic knob-and-kettle topography. Mounds, 1-10 m high and 10-30 m wide, are separated by 5-30 m wide, several meters deep, irregular depressions. The upper surfaces of the mounds are covered by angular to subangular limestone pebbles and blocks and internal sediments show a typical diamicton appearance with pebbles suspended in a muddy to sandy matrix. These chaotic structures are interpreted as hummocky disintegration moraines from former active glaciers. Successive cross-valley morainic ridges, up to 200 m high and several hundreds of meters long, limit the down-valley extension of these hummocks, and are interpreted as ice-marginal moraines. In the tributary Susam Valley, part of the coarse loose material forms a 200-250 m long and 90-120 m wide tongue-shaped structure with successive arcuate ridges and furrows at its down-valley reach. This structure, which is connected upward to a talus slope and perched cirque, resembles the morphology of a periglacial rockglacier but is interpreted as the disintegration moraine controlled by small periodic retreat and readvance of the last active ice-front in this region.
