The Motorchuna (
The name of the river comes from the Even "mo/tor/chu" (мо/тор/чу), meaning "tree/pass/river".[2]
In the International scale of river difficulty the Motorchuna is a Class II destination for rafting and kayaking.[2]
Course
The sources of the Motorchuna are north of the Polar Circle, in the northeastern slopes of the Central Siberian Plateau, very near the sources of the north-flowing Merchimden. It fringes the plateau area heading in a roughly ENE direction. In mid course it turns slightly and flows across the Central Yakutian Lowland in a roughly ESE direction forming meanders in the floodplain to the south of the Syungyude. The banks in the middle and lower reaches are bound by vertical rocky cliffs. The channel is mostly pebbly. In its last stretch the Motorchuna flows parallel to the Muna further south, in an area of lakes and marshes. Finally it meets the left bank of the Lena, 606 kilometres (377 mi) from its mouth. Its confluence is almost opposite the mouth of the Menkere on the facing bank.[3][4][5]
The Motorchuna is fed by rain and snow. It freezes in mid-October and stays under ice until late May or early June.[2]
Tributaries
The Motorchuna has fifty tributaries that are over 10 km (6.2 mi) in length. The longest ones are the 147 km (91 mi) long Byuger-Yuryach and the 132 km (82 mi) long Kuogas-Uluybut, both joining it from the left.[2][1]
