 The finds from Berelekh. ( The map of main finds of mammoths in Siberia )
  In 1970 the searching works began at the huge mammoth's cemetery near the stream Berelekh in Yakutia. The expedition was headed by known palaeontologier professor N. Vereschagin from the Leningrad Zoological Institute. Scientists for a long time received the messages about the powerful layer of bones in the valley of Berelekh, and arrived to the place for the first time they were amazed with its sizes. Accumulations of bones were extended on 180 meters along a coastal steep bank. The thickness of the bones layer reached 2 meters. Scientists began to work. However it was not simply to collect the bones.
  The ground in polar tundra freezes on some meters, and for short summer thaws only on some centimeters. It is difficult to separate bones from the frozen ground, even they lay on the surface. And the large part of fossil remains, mixing up with sticky silt and water, has turned for long years to an ice impenetrable mass. The digging out of bones by a shovel or breakage became too hard. The scientists were ready for work in such conditions and have brought the pump themselves , approximately such as firemen use. The powerful jet of water washed away ice and ground, cleaning the bones. But even with such equipment the work went slowly, it was possible to wash out only a few ten centimeters of ground per day. But the rezults were obtained stunning. 8,5 thousands of bones from 140 mammoths were cleared and prepared to transportation after some weeks of work, the tests of grounds and vegetation for laboratory analyses were taken. But mainly in 200 meters from mines of bones  stone tools of ancient hunters were found.
  Already in Leningrad it was turned out after the studying of expedition materials that this mammoths cemetery formed in the end of the last Glacial Epoch, about 12 thousand years ago. In this place bodies and bones of animals were brought by movement of the ancient stream Berelekh . For years they were accumulated here, and gradually covered by layers of silt and froze in the ground.
  Further it was understood the palaeolithic stand located near the cemetery. Ancient inhabitants of these places came to the stream bank for searching more fresh meat, they fished out the lost mammoths and killed wounded ones. At the place of the stand the numerous stone tools and ornaments from jade were found, and professor Vereschagin detected in the bones layer the tip of spear from splitted mammoth tusk.
