If the reason is falling celestial body, the earth to stay its traces. Earlier group of geologists from the University of Bologna found that the bottom of Lake Cheko, located in the Evenki autonomous district, similar to the crater formed at falling celestial body. Ceco morphology is different from other Siberian lakes that can not be explained by normal processes of erosion and sedimentation, Italian geologists believe. The data show that the age of the lake does not exceed 100 years, that is, it could not previously formed in 1908 Luca Gasperini (Luca Gasperini), Enrico Bonatti (Enrico Bonatti) and Giuseppe Longo (Giuseppe Longo) studied Lake Cheko using their own vessel. As the lake is located in remote areas, reliable data on his age in the form of maps and reports of local residents does not exist. Scientists used hydro-acoustic, radar, biological and chemical methods. The work was built stratigraphic model of the lake bottom, it Bathymetric Chart, a chemical analysis of lake sediments. The method of annual rings of trees adjacent investigated age. All data indicated that the age Ceco should not exceed 100 years, which is consistent with the hypothesis that it was formed in 1908 as a result of falling celestial body. In the future, Italian scientists are planning to return to the lake and carry out drilling its bottom.
