Macroscopic Description: Kathleen McBride
The exterior is a dull dark gray color. The interior of this carbonaceous chondrite is a muddy gray with no distinctive features.

Thin Section (,2) Description: Tim McCoy
The section consists of a few small chondrules (up to 0.5 mm) that have been completely replaced by phyllosilicate set in an Fe-rich serpentine matrix. No isolated mineral grains or CAIs are apparent; sulfide and carbonate grains are present. Unaltered olivine or pyroxene grains of sufficient size for microprobe analyses were not found. The meteorite is a highly altered CM chondrite probably of petrologic type 1.
