Origin of sabalan Rock glaciers case study of rock glacier at north slope of Haram summit

Surface and internal characteristics of tongue-shaped rock glacier have been studied at the north slope of Haram summit on interior Sabalan Mountain. The formation of surface depressions indicates the existence of a solid ice core, and its origin also is determined by using RILA concept. It is probable that a normal glacier has been buried beneath a cover debris. The vertical section of this rock glacier shows three layers from bottom to top, and based on the dynamic criterion, the rock glacier is an active one.
