Shirvan valley (Erosion- Volcanic phenomenone)
At a northern zone of Sabalan summit is seen a long and rather deep valley that has very beautiful and wonderful landscapes. This valley has been caused by the flooding erosion at Sabalan volcanic and pyroclastic sediments. The very beautiful erosion shapes consist the erosion columns, conglomeratic columns and in general, one very will and rough structure is seen at this valley. The walls and valley section shows a good layering at a volcanic material
