Mt. Aag. 2310 m, cat. 1B, to the 3rd slope, M. Ostrogorsky. 1977.
From the base camp located on the Dremuchiy stream. The approach to the western slope is along a flat valley of lava fields.
The ascent begins on a wide ridge along a snowy slope covered with large slag (see photo).
Further along the ridge to the snowy ascent with small rock outcrops, the ascent is along the rocks to the shoulder.
From the shoulder, the ascent is along the snowy slope to the summit dome.
The entire route is traversed simultaneously.
The ascent time is 5–6 hours.
The descent from the summit is via the ascent route. However, it is possible to descend from the dome into a wide couloir leading to the west parallel to the route. It is safe and very convenient for skiing down.
