The Katun ( Russian Катунь ) is the 688 km long left source river of the Ob in the south of Western Siberia ( Russia ). It is also named for the Katun chain, which he encircles on three sides, in the center of the High Altai or Russian Altai .
course
The river has its origin about one kilometer away from the Russian- Kazakh border on the southern flank of the 4506 m high Belukha , the highest peak of the Altai and all of Siberia . There it flows from the Gebler Glacier .
The Katun continues to flow west and after about 60 km turns north to circle the Katun mountain range in an elongated, semicircular arc. Exactly north of the approximately 120 km long massif, the milky-white glacial waters of the Kutscherla and Akkem flow into it . The main access to the three highest peaks runs through the high valleys of these water-rich tributaries.
Then (at around 300 km) the Katun finally turns its course to the north and swings into a striking longitudinal valley from which a strong tributary drains the border mountains to Mongolia . At Inja , where the M52 trunk road crosses the valley, the waters of the Tschuja come from the southeast . The relatively straight longitudinal valley is now the breakthrough so closely by a rugged mountain land that otherwise the Katun following highway in a western tributary dodge needs.
Before the Katun emerges from the mountains, it passes Chemal and Ust-Sema , from where the M52 can now follow the river again, and about 70 km further on Maima , a suburb of Gorno-Altaisk , the capital of the Autonomous Republic of Altai . About 100 km down the valley below Bijsk the Katun joins the somewhat smaller Bija to the Ob.
Expeditions
In 1826 the Baltic German Alexander von Bunge traveled with Carl Friedrich von Ledebour to the Altai Mountains, where Bunge continued to travel until in 1829 he reached the sources of the “Katunja”. The research results of this trip are in “Karl Friedrich v. Ledebour's journey through the Altai Mountains and the Djungarian Kyrgyz steppe… ”(Berlin, 1829–30). Ledebour's publications “Flora altaica” (1829–33) and “Icones plantarum novarum vel imperfecte cognitarum floram rossicam, imprimis altaicam, illustrantes” (1829–34) also testify to this expedition.
The Gebler Glacier is named after the German-Russian doctor, naturalist and explorer Friedrich August von Gebler (* 1782 in Zeulenroda , † 1850 in Barnaul ), from whom the first detailed description of the Belucha area (1836) and many other parts of the Russian Altai originates.
