Submission + - Tunguska Impact Crater "Found" (bbc.co.uk)
BigBadBus writes: "An Italian Team is claiming to have found the impact crater resulting from the 1908 Tunguska impact.
From the BBC website:
A University of Bologna team says a lake near the epicentre of the blast may be occupying a crater hollowed out by a chunk of rock that hit the ground. Lake Cheko — though shallow — fits the proportions of a small, bowl-shaped impact crater, say the Italy-based scientists. Their investigation of the lake bottom's geology reveals a funnel-like shape not seen in neighbouring lakes. In addition, a geophysics survey of the lake bed has turned up an unusual feature about 10m down which could either be compacted lake sediments or a buried fragment of space rock."
Of course, this is highly controversial, but its a hell of a lot better than the gas eruption theory mentioned in one of Arthur C.Clarke's "Mysterious World" books."
