On the Trail of the World's Great Meteorites
University of New Mexico Meteorite Collection
On Oct 4 2023, I was thrilled to be part of a small group permitted to tour the impressive UNM meteorite collection in Albuquerque.
Special thanks to Dr. Carl Agee for hosting our group and showing us these amazing specimens.

Norton County
Kansas - 1948. Aubrite (Enstatite Achondrite)
This massive centerpiece of the UNM collection, Norton County fell as a widely witnessed fireball and meteor shower across the Kansas - Nebraska border in Feb 1948. The UNM sent a team and recovered many pieces. This is the largest piece, 1070 kg, recovered 3 months after the fall from Nebraska. It is the largest single stone meteorite to fall in the USA. Aubrites are named for the 1836 Aubres, France meteorite. They are rich in magnesium. The interior is creamy white and quite fragile. Forsterite makes up about 10% of this meteorite, and it fluoresces yellow under UV light. The parent body source of aubrites may be the asteroid 3103 Eger.

Navajo
Arizona - 1921. Iron.
This huge meteorite piece (named Navajo I - 3306 lbs) was found in 1921 buried under some rocks and talus and beads below a sandstone ridge. A second piece (Navajo II - 1508 lbs) was found nearby buried in soil, 5 years later. There is evidence the Navajo and pre-historic people knew of both these objects.
The Navajo I meteorite was cut and polished at the Smithsonian in 1991. This display piece from Navajo I is 1600 lbs. It is on long-term loan from the Field Museum in Chicago.

This 160 kg stone was found while plowing.

This unique meteorite was purchased in Morocco in 2011. It contains a number of different clasts of rock and mineral types (lithologies) of various sizes and shapes in a black matrix. It has a high water content. It has been extensively studied and is felt to be a sample of ancient Mars crust.
