Dear List:

It looks like Bernd got the following but no one else did, because of a
missing hyphen -. Here are the statistics, showing the latest Canadian
meteorite ranks as #22 in mass on the TKW scale. It is the second largest
stony meteorite FIND in Canada, after Vulcan, but not the second largest
meteorite found in Canada, nor the second largest stony meteorite found in
Canada.

Dear Bernd:

Hi. The TKW of Iron Creek was less than originally reported (386 lbs).
How do we know this? The meteorite was re-weighed in 1999 and presently
the main mass is now 145.25 kilos. Not enough has been distributed to
account for 30 kilos, nor is there enough cutting to suggest that amount
was removed, in fact far less is indicated, maybe as little as a
kilogram.

Here's my e-mail to Monica Grady of June 1, 1999, referred to in the 5th
Edition Natural History Museum Catalogue:

=========================================================

>Dear Monica: As a result of recent discussions, the Curator at the
>Provincial Museum of Alberta, Ron Mussieux, has confirmed that the
weight of
>the main mass of the Iron Creek, Alberta iron meteorite is now about
320 lbs
>or 145.25 kilos. The original mass is recorded everywhere as 386 lbs
or
>over 175 kilos. As there is no evidence that 66 lbs of the meteorite
has
>been distributed elsewhere, i.e. far less is recorded in other places
and
>there is no evidence of where 30 kilos could have been removed, it
appears
>that the original weight was in error. A consequence of this is that
the
>Madoc, Ontario iron meteorite at 167.5 kilos original mass now is the
>heaviest/largest found in Canada.

>Please contact Ron at <RMussieux_at_mcd.gov.ab.ca> to confirm this for
revision
