The Bur is a left tributary of the Olenyok. Its sources are in a hilly area of the North Siberian Lowland, in the vicinity of the sources of the Udya and the Buolkalakh. It flows across a marshy floodplain with small lakes, meandering strongly and flowing roughly eastwards north of the Beyenchime. Finally it joins the left bank of the Olenyok river  upstream of its mouth. The confluence is only a little downstream from the mouth of the Khorbusuonka in the opposite bank. The river is frozen between early October and late May. The Bur has several very long tributaries, such as the  long Ary-Ongorbut, the  long Kyra-Khos-Toryuttyakh and the  long Noyuo from the left, as well as the  long Kyuntyukelyakh from the right.
