Possible crater from the Tunguska blast found

Researchers from the University of Bologna in Italy have identified what might be a crater from the Tunguska blast in 1908. The alleged crater is a bowl-shaped lake that seems to be a recent geological feature. There's evidence of buried rock beneath the lake that could have come from an asteroid or cometary remnant. And a few other details seem to jibe well, too. Very cool stuff if this bears out: the Tunguska event is perhaps the most frustrating natural disaster in modern history, since it was two decades before the Russians were able to send a team out to study the site. We still don't know what happened that day, 'cept it was detected as far away as England and it knocked horses plum off their legs for hundreds of miles around.
