N2 - A well-known Russian geographer Andrey Kapitsa is one of the authors of discovery of the Antarctic subglacial Lake Vostok. From 1995 to 2015, the Russian Antarctic Expedition carried out specialized seismic and ground radar studies of morphometric characteristics of this lake and continued drilling the deep ice borehole at Vostok station. In 2012 and 2015, the drilling operations reached the -ice-water‖ divide at a depth of 3769 m. In 2018, study of Lake Vostok was suspended with priority given to a search of the most ancient ice in Antarctica. The most widespread hypothesis of the origin of lake water body is melting of the lower glacial surface. An analysis of rift-related origin of the lake valley, existence at the lake bottom of earthquakes and geothermal flows and a by-layer character of the glacial structure showed the lake water strata to exist even before the glaciation epoch of Antarctica more than 35 million years ago. Negative results of mathematical modeling of the possibility of lake through freezing to the bottom confirm this fact. Thus, water and bottom sediments of Lake Vostok are by their age more ancient than the glacier above them.
