Could a crater solve the 1908 meteor mystery?

In late June of 1908, a fireball exploded above the remote Russian forests of Tunguska, Siberia, flattening more than 800 square miles of trees. Researchers think a meteor was responsible for the devastation, but neither its fragments nor any impact craters have been discovered so far. Italian researchers now think they’ve found a smoking gun: the 164-foot-deep Lake Cheko, located just 5 miles northwest of the epicenter of destruction.
