I'm pretty sure I read somewhere that the -Tagish Lake meteorite(?)- had
that exact characteristic, making their winter gathering that much more
frantic, as it would literally turn into a mud in the thaw...

Okay, all meteorites are subject to weathering away to greater or lesser
degrees, of course. But
what about the idea of "a type of meteorite that dissolves in water and with
the following rain
there may be nothing to find,"?

Murchison's meteorite theory gains momentum

Murchison's meteorite mystery is a step closer to being unravelled, with two
people confirming they
saw a dazzling display in the night sky which is consistent with a meteorite
shower.
Like many other Murchison residents, Sandy Matthes, who runs a backpackers'
hostel in Stevenson St,
heard a loud bang at 9.15 pm on July 10.

"I heard a boom and then saw a flash and the stones falling like stars -
they were glowing red like
they were on fire," Mrs Matthes said.

An English backpacker returning to the hostel joined Mrs Matthes in the
street to watch the
spectacular light show, but he left town two days ago without revealing his
part in the Murchison
meteorite mystery.

"It was like hundreds of little stars falling down, it was a very good
experience for me, it was
amazing," Mrs Matthes said.

"I was so lucky to be outside."

Antique store owner Betty Maslin said another resident told her he was out
getting firewood and also
saw the flashes in the night sky.

"There is no doubt now that we have been struck again," Mrs Maslin said.

A meteorite famously hit the town in September 1969.

The largest piece of the carbonaceous chondrite weighed 7 kg and contained
numerous amino acids and
a variety of other organic compounds that are thought to have played a role
in the origin of life.

Comet enthusiast David Seargent, who wrote two books on the original
Murchison meteorite, said the
latest mystery was intriguing.

"There are some things about the reports that point to another meteorite and
other parts of the
story that don't quite fit," he said from his home on the NSW central coast.

Mr Seargent said witness accounts of objects glowing red like fire could
have been a meteorite.

"The other possibility is space junk, which can often produce a fireball,"
he said.

Despite numerous reports of fragments hitting houses in Murchison, no pieces
of rock have been found
to date and Mr Seargent said solid evidence might not exist.

"There is a type of meteorite that dissolves in water and with the following
rain there may be
nothing to find," he said.

One troubling aspect of the meteorite theory is that the reports are only
coming from a small area
of Murchison.

"Such an event would have been visible across a wide area of Victoria," Mr
Seargent said.

"If it was only seen in Murchison it does not fit with a meteorite landing
or space junk falling to
earth."
