The Aag is destroyed volcano with traces of glacier treatment of the second phase of the Upper Pleistocene glaciation. The primary slopes of the volcano are preserved in the form of separate plateau-like remnants in the lower part of the structure. According to spore-pollen analysis (I.A. Egorova), the volcano formed in the first half of the Upper Pleistocene. The volcano is composed of powerful flows (60-100 m) of light gray dacites and andesidacites.
