The Podkamennaya Tunguska is an eastern, right tributary of the Yenisey. It is long, and has a drainage basin of. The name of the river comes from the fact that it flows under pebble fields without open water. As early as 1610 Russians from Mangazeya had passed the Podkamennaya Tunguska's confluence with the Yenisey; by the 1620s Mangazeya Cossacks and trappers had ascended it seeking fur-tribute from the local Tungus clans. The Tunguska event in June 1908 occurred near this river, some SSE of Lake Cheko.
In its upper reaches the river is known as Katanga. Its valley forms the northern boundary of the Yenisey Range, north of which rises the Tunguska Plateau. The main tributaries of the Podkamennaya Tunguska are the Tetere and Chunya from the right, and Kamo and Velmo from the left.
