From 1926 through 1930 Yevgeny Krinov worked in the meteor division of the Mineralogy Museum of the Soviet Academy of Sciences. During this period he conducted research into the Tunguska event under the supervision of Leonid Kulik. Krinov took part in the longest expedition to the Tunguska site in the years 1929–1930 as an astronomer. The data that was gathered during this expedition became the basis for his monograph called The Tungus Meteorite, 1949.
In 1975, Yevgeny Krinov ordered the burning of 1500 negatives from a 1938 expedition by Leonid Kulik to the Tunguska event. It was done under the pretext that they were a fire hazard, but the truth may have been the active dislike by official meteorite specialists of anything associated with an unyielding enigma. However, positive imprints could be preserved for further studies in the Russian city of Tomsk.
