This place is well-known for its harsh winter, temperature once droped to negative 62 C. Summer is unbearable hot. But these places attract many people cause of extraordinary beauty around.
The biggest part of Aktru glaciers is located in Aktru canyon at height 2150 meters.
Alpine Aktru basin topography formed by weathering and water-glacial erosion acting on uneven tectonic uplift of individual blocks of the array. Therefore, rised high mountain ridges (the highest peaks reach 4000 m) adjoin deep landforms, numerous potholes, niches and different kinds of grooves. Such relief assisted to the accumulation of snow and formation of ice of glacial era, which advanced twice in Altai. Glaciers occupy about 16 square kilometers.
There are 5 glaciers in Aktru basin: Small Aktru, Large Aktru, Waterfall Glacier, Kyzyl-Tash, Kyrkyrek.
Ice stream of Small Aktru is snowless, falling to height 2235 meters. Streams flowing beneath the glacier combine together forming small Aktru river. In the bottom edge of glacier created gaps are temporary ice caves, providing a rare opportunity to see inside a glacier. Inconspicuous hole in the bottom leads to the hall with a dazzling blue vaults under the dirty, sand-strewn surface of the glacier. Ice stream feeding Aktru runs in the middle of the cave, reflecting the blue jet vaults. The light on the irregularities of the walls and thickness of the ice above create a completely fantastic scene, it seems as a cave emits a blue glow.
On the north side of Kara-Tash Mountain at the altitude of 3600 m a small glacier (about 1 sq km area) is overhung. The short side of the top of a spur divides it into two sleeves, similar with legs, so the glacier has the informal name «Tronov pants». Its thickness is about 170 m, which correspond to the time span of 700-800 years according to researchers. It was selected by researchers of international Russian-Japanese-American team for monitoring environmental changes. Deep fissures cut surface of the glacier. It is active in developing its glacier bed, so walking on is safety in early spring only, rockfalls are often in summer.
Waterfall Glacier Name «waterfall Glacier» connected with the small stream flowing from the ice stream forming lovely waterfall below. It is located in the upper reaches of peak «Dome of three lakes» (3556 m). Waterfall Glacier is relatively safe for passage and free-ride, since almost has no cracks and fractures. The area of glacier Waterfall is about 0.77 km². Large Glacier Aktru.
Large Aktru area is about 11.3 m² with length of more than 8 km. It refers to glacier of valley type. Glacier Large Aktru is divided into two asymmetrical sleeves (left and right Aktru) which combined in a single channel at the bottom. Thickness of the ice reaches 350 meters. Beautiful blue Lake with surprisingly deep turquoise water color is located on the glacier Large Aktru in moraine pocket at an altitude of 2840 meter. Flow of Aktru River formed by ice streams running between «Muttom foreheads» originates here. The highest peak of the area, Aktru-Bash (4075 meters) is also here.
