Bolshoy Pit

The Bolshoy Pit (Большой Пит - "Great Pit") is a river in Krasnoyarsk Krai, Russia. It is a right hand tributary of the Yenisey.

The Bolshoy Pit is 415 km long, and the area of its basin is 21700 km2. The lower reaches of the Bolshoy Pit are navigable during the spring flood between May an June up to the village Bryanka, 184 km from the river's mouth.

Course
The Bolshoy Pit has its source in the eastern slopes of the Yenisey Range, part of the western side of the Central Siberian Plateau. Its source is not far from the source of the Velmo, a tributary of the Podkamennaya Tunguska. After 15 km, it is joined by the Maly Pit. Flowing southwestwards across the taiga of the mountainous region, it cuts across the main ridge of the Yenisey Range through a deep gorge. Then it bends and flows roughly northwestwards in the last nearly 100 km of its course.

The Bolshoy Pit joins the right bank of the Yenisey 5 km downriver from Ust-Pit village and 1880 km from the mouth of the Yenisey. The confluence is located between the mouths of the Angara and Podkamennaya Tunguska. The river freezes in mid-November and stays frozen until mid-May.

The main tributaries of the Bolshoy Pit are the Chirimba, Panimba, Veduga, Lendakha and Kamenka on the right and the Gorbilok and Sukhoy Pit on the left.
