The mouth of the Barguzin, hot springs exist.
Lake Baikal receives over 300 streams, mostly short mountain torrents, besides the Upper Angara, which enters its north-east extremity, the Barguzin, on the east, and the Selenga on the south-east.
Above the lake), falling with steep cliffs towards the lake, fringes it on the south; a massive, deeply-ravined highland occupies the space between the Irkut and the Angara; the Onot and Baikal ridges (also Primorskiy) run along its northwest shore, striking it diagonally; an Alpine complex of yet unexplored mountains rises on its north-east shore; the Barguzin range impinges upon it obliquely in the east; and the Ulanburgasu mountains intrude into the delta of the Selenga.
But around and north-east of this lake the same wellmarked ranges fringe the plateau and turn their steep north-western slope towards the valleys of the Irkut, the Barguzin, the Muya and the Chara, while their southern base lies on the plateaus of the Selenga (nearly 4000 ft.
Farther east, on the southern shore of Lake Baikal, Khamar-daban rises to 6900 ft., and the bald dome-shaped summits of the Barguzin and southern Muya Mountains attain elevations of 6000 to 7000 ft.
This conformation is seen in the valley of the Us in West Sayan, in that of the upper Oka and Irkut in East Sayan, in the valley of the Barguzin, the upper Tsipa, the Muya and the Chara, at the foot of the Vitim plateau, as also, probably, in the Aldan.
