Tunguska mystery crater might be found
------------ -------- -------- -------- -------- ---

"Crater Could Solve 1908 Tunguska Meteor Mystery"
(Source: 6/26/07)

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.

Astronomers have been left to guess whether the object was an asteroid
or a comet, and figuring out what it was would allow better modeling
of potential future calamities.

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.

Students will
(E.O.A.S.1) Compare the explosion results of the June 1908 Tunguska, result of Meteor Crater in AZ, and the Krakatoa volcanic explosion in the 1800's.
