The Sob flows across the Priuralsky and Shuryshkarsky districts. The Salekhard–Igarka Railway stretch of the Northern Railway runs along the valley of the Sob in the Polar Urals. Since it is of relatively easy access, the river has become a tourist attraction as a Class I to IV destination for rafting and kayaking.[2]

Course

The Sob is a left tributary of the Ob river. It has its sources in the eastern slopes of the southern sector of the Polar Urals. After leaving the mountainous area, the river flows roughly southeastwards and southwards among small lakes in a floodplain located at the northwestern end of the West Siberian Plain. Kharp town is located by its banks in its middle course. The area is marked by permafrost, being often swampy, and with patches of tundra and coniferous taiga. Finally the Sob meets the left bank of the Ob near Katravozh, about 322 km (200 mi) from its mouth.[3][4]

Tributaries

The main tributaries of the Sob are the 55 km (34 mi) long Bolshaya Pai-Pudyna (Большая Пай-Пудына) and the 54 km (34 mi) long Khanmei (Ханмей) from the left, as well as the 54 km (34 mi) long Orekh-Yugan (Орех-Юган) and the 36 km (22 mi) long Yenga-Yu (Енга-Ю) from the right.[1] The river is fed predominantly by snow and is frozen between October and June.[3][1][5]

Fauna

The main fish species in the river are muksun, peled, broad whitefish, nelma, and sturgeon. [6]
