Image of the Lake Cheko bottom, at ~40m of water-depth, collected by Luca Gasperini using an underwater video camera (kindly provided by Communication Technology, Cesena) during the Tunguska2008 recognition.

The 30 June 2008, one century after the Tunguska Event, our researchers observed for the first time the bottom of the lake. The bottom appears to be carpeted by tree trunks and branches, which are covered by a thin veneer of mud. We are analysing data to gather information regarding the nature of these trees and the reason why they cover the lake floor.

Here, you can download the direct registration of the 30 June 2008 flight (1' 31") to the Lake Cheko and of the first video exploration of the lake bottom: (part 1, 1' 08") and (part 2, 1' 25")
