Roberto writes:
New addition to the collection: 4.58g slice of Casas Grandes.

According to metbul, Casas Grandes is classified as an IIIAB Iron meteorite with a TKW of 1.55t. This meteorite is interesting because of its history and how it was found.

The 1.55t mass was found in 1867 in the temple ruins of Casas Grandes in Chihuahua, Mexico. It was found “incased in wrappings similar to those surrounding the bodies in the neighboring graves“ (Farrington, 1901).

This slice was taken from a larger slab that originally came from the Smithsonian Institute. It is displayed with a piece of Mata Ortiz, or Casas Grandes, pottery by Chele Acosta.

I would like to thank Doug Achim (IMCA# 6767) for this beautiful slice. I would also like to thank Rob Wesel for providing me with an in-depth history of this very interesting find.

Yes, the ruins at Casas Grandes (Paquim*) are about 6 miles west of the given find location and the modern village of Mata Ortiz is about 13 miles south southeast of Paquim*. Interestingly to some, Paquim* is due south of Chaco Canyon in New Mexico, some 400 miles away. Just for the record, it is the Smithsonian Institution, not Institute.

The link to Buchwald is above, just after the TKW info.

I collect NA pottery, and immediately thought of Mata Ortiz when I saw the small pot next to your sample. I didn't know the two were in such proximity. Nice!

Yes, great meteorite, and great story. And if you want to know more go to the "Handbook of Iron Meteorites: by Vaugh Buchwald. You can find a link to it on the Met.Bulletin. In 1876 it was hauled on a wagon from Casas Grandes to San Antonio, Texas (about 1000 miles/1500km)and Luling and put on a train to the Philadelphia and the World's Fair.

Cool story! Remembers me of the story of the Elbogen iron, the bewitched Burggrave. Maybe someone of the tribe was lost while others found the iron?
