, and has depth up to 325 meters. Situated at a height of above the sea level, the lake is long and wide and lies between the mountain ridges Korbu and Al-tyntu, on the junction of the Sailughem Mountains and the Western Sayans. Its surface area is ; however, due to its considerable depth (), the lake contains no less than 40 km³ (9.6 cubic miles) of fresh water. Annual water level fluctuations are estimated at some 348 sm. The lake transparency is high, with the visibility of the lake water ranging from six to fourteen meters. About 70 rivers and 150 temporary streams flow into the lake, the largest of them,

have a legend about the name of the lake in their language, which means Golden Lake. According to this story, once, a rich man had an ingot of gold, which he wanted to use to buy food. He travelled around Altai, but could not find anyone who would sell him any food. Eventually, he threw the gold into the lake. This legend is the origin of the name.

There is a field base of Institute of Taxonomy and Ecology of Animals (russian: Институт систематики и экологии животных СО РАН) by the Siberian Division of the Russian Academy of Sciences (russian: Сибирское отделение Российской академии наук) at the northwest part of the lake, about 6 km from head water of

works in the Teletskoye geology-prospecting detachment searching for gold-placers. They managed to establish a new search criterion for a placer. The base for the discovery were the palaeoglaciological studies during the last few years and theoretical models of the diluvial morpholithogenesis. The content of the precious component is everywhere much higher than the lowest accepted industrial standard, sometimes it’s tremendous. The investigators carried out large-scale exploration routes on vast territories near watersheds of the upper reaches of all the rivers in the northern and western parts of the Teletskoye Lake basin. These explorations included studies of exposures, boring of prospect-holes, pits and hollow wells (up to 15 m deep). The results of these investigations let us speak about the regularity and reliability of the new criterion. The first 14C-method data for the layered
