Abstract. Systematized are the Munku-Sardyk high-mountain landforms originated due to exogenous processes of different genesis, age and location. Ancient: supraglacial preceeded Oka and sin-Oka very long development; subglacial progressive stage of Oka; subglacial regressive stage of the Okinsky glacier that developed in areas of relief development of the previous type; subglacial, developed on the periglacial relief of the first type, regressive, after thermal glaciations. Modern: nival-glacial, permafrost and erosion processes that are consistent (developing) with the vertical geocryological zonation of the regressive stage of glaciation: periglacial physical weathering and snowfields developing above modern glaciers and stone glaciers; glacial — within the development of modern glacial processes; solifluctionary; high-altitude-aufeis; mudflowers; permafrost-stone mountain streams and erosion activity of mountain rivers. Landforms resulting from all the above processes are complicated by denudation-accumulation slope processes.

Keywords: Munku-Sardyk Range, high-altitude landforms, genesis of landforms.
