By the Byoryolyokh, more than 8,000 bones from at least 140 woolly mammoths have been found in a single spot, apparently having been swept there by the current.[2]
The name of the river is based on the Yakut languageБөрөлөөх, Börölööx, meaning "teeming with wolves."[4]
Course
The source of the Byoryolyokh is located at the confluence of two small rivers north of the Polousny Range. The river flows roughly northeastwards across the Yana-Indigirka Lowland. The length of the Byoryolyokh is 754 kilometres (469mi). The area of its drainage basin is 17,000 square kilometres (6,600mi2).[5]
The river is also known as "Yelon" (Russian: Елонь) in a section of its lower course. It joins the Indigirka from the left at the Russo-Ustinsky Canal, the western arm of the Indigirka River near its mouth, not far from Chokurdakh.[6]
There are more than nine thousand lakes in the basin of the Byoryolyokh River. It usually floods over its banks in July and August. In winter it freezes to the bottom.[7]
