The Huffington Post UK reported this morning that divers have found [a

article also reports that soldiers found a six-meter fragment of the
meteorite on the lake's shore. I have seen no independent confirmation
of these reports.

Me either. Reports out of Russia are always problematic, given the
credulous nature of so much of its population. Everything is made more
difficult by the difficulty involved in foreigners being allowed into
this area.

The last I've heard is that no meteorites have been recovered yet, and
the Russian military has given up looking in Lake Cherbakul, and
claims the hole was made by something else. Certainly, holes in open
ice are not uncommon- warm convection currents, gas bubbles, and other
things create and maintain them.

It is quite remarkable that no meteorites have been recovered, given
the size of this event. Fireballs of this sort typically produce
large, obvious strewnfields.
