Two kilometers from Lake Cheko on the banks of the Kimchu River in a deserted area just 8 kilometers from the place of the fall of the Tunguska meteorite, a very unusual object with all the signs of artificial origin is clearly visible on satellite images.
Cheko is a fresh lake in the Krasnoyarsk Territory. It is located approximately 760 km north-east of Krasnoyarsk and only 8 kilometers north-west of the epicenter of a possible fall of the Tunguska meteorite. Cheko is not marked on any map drawn up before 1929, which may be due to poor knowledge of the area.
The Kimchu River flows through the lake. It flows in in the west, also flows out in the west, but to the north. The lake belongs to the river basins: Chunya, Podkamennaya Tunguska, Yenisei.

A group of Italian geologists from the University of Bologna, led by Luca Gasperini, hypothesized that the crater of the Tunguska meteorite could be Lake Cheko on the Kimchu River, located just 8 kilometers northwest of the well-known epicenter of the explosion.
Lake Cheko has a depth of up to 50 m and a conical bottom. This morphology, different from other Siberian lakes, cannot be explained by the usual processes of erosion and deposition, they argue. In 2008, scientists planned to test the bottom of the lake. They presented their research in 2007 articles “Found crater as a possible result of the 1908 Tunguska meteorite” (“A possible impact crater for the 1908 Tunguska Event”) and 2008 “Tunguska meteorite and Lake Cheko: a causal relationship or its absence? " ("Lake Cheko and the Tunguska Event: impact or non-impact?"). Scientists have applied hydroacoustic, radar, biological and chemical methods. In the course of the work, a stratigraphic model of the lake bottom, its bathymetric map, and chemical analysis of lake sediments were carried out. The age of adjacent trees was studied using the tree ring method. All data indicated that the age of Lake Cheko should not exceed 100 years, which is consistent with the hypothesis that it was formed in 1908 as a result of the fall of a celestial body. In addition, studies have revealed a large reflective object, hidden 10 meters below the bottom of the lake, which may be the remnant of a space body.
