Rock glaciers are one of the distinct geomorphology feature are seen in medium size at Sabalan mountain slope. Active rock glaciers represent the existence of Alpine permafrost, and on the other hand these features sigificant tools for palaeoclimate reconstructing. About 14 rock glaciers at the North slope of Sabalan at the height of between 3460 and 4400m S.L. has been distinguished. That about cover an area of 6.29 km. Tongue-shaped rock glaciers with 85.1 percent have the highest spread than lobate rock glaciers with 14.3 percent. Their area varies from 0.05 to 1.64 km, and their formation at present time depends on the regional topoclimate. By using the RILA and RLA concepts their origin has been distinguished. On the basis of their moving rate in a year the probable age of active rock glaciers can be estimated between 3000-6000 years.
