Tunguska Crater Found?

["Richard W. Travsky" <rtravsky@uwyo.edu>]

Slightly off topic. I can understand the difficulties in finding and 
identifying a 65 my old crater, but one barely a hundred years would seem
to be easier ;)  Saw this on the BBC site and then on Nature...

After nearly 100 years of searches, researchers have found what may be an 
impact crater made by the object that caused a huge blast over the remote 
Siberian area of Tunguska on 30 June 1908.

Others caution that the identification of the crater remains to be proved, 
but say it could be an important discovery and merits further study.
