A small lake in Siberia may be a secondary impact feature from the famous 1908 Tunguska event:

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

I personally knew one of the authors of the article (Giuseppe Longo) when I was studing at University of Bologna. I recall they were already making scientific expeditions to Tunguska, it was 17/18 years ago... Hope they will be able to recover impactor fragments in the lake (if any).
