Akitkan Range

Between 1855 and 1858 Ivan Kryzhin (d. 1884) took part in the Eastern Siberian expedition led by Russian astronomer and traveler Ludwig Schwarz. In 1857 he mapped the Kirenga River and, while exploring its right tributary, the Cherepanikha, Kryzhin discovered the formerly unknown Akitkan Range rising above the area of its source. The North Baikal Highlands, where the range rises, were explored between 1909 and 1911 by Russian geologist Pavel Preobrazhensky (1874 - 1944). He surveyed the river valley of the Chechuy, a right tributary of the Lena with its sources in the Akitkan. Overcoming numerous difficulties, Preobrazhensky managed to map for the first time a stretch of the Akitkan Range. ==Geography==

The Akitkan stretches roughly northwards for over from the northern end of the Baikal Range, northwest of Lake Baikal. It is limited by the Cis-Baikal Depression (предбайкальская впадина) to the west, the Lena to the north and the Chaya river valley to the east. To the southeast rises the Synnyr. The highest summit is a high unnamed peak located at the southern end, west of the Ungdar Range. The heights of the range summits decrease from circa in the southern section to in the northern. ==Akitkan Orogen==

The Akitkan Orogen forms a suture between the Anabar Shield to the northwest and the Aldan Shield to the southeast. It is a feature of the Siberian Craton known only from geophysical data along most of its extent because it is covered by younger rocks. ==See also==
