Macroscopic Description: Kathleen McBride
The exteriors have dull, rough, black fusion crust with pits and polygonal fractures. The interiors reveal a brown-black matrix with mm-sized clasts and chondrules. Colors range from white to tan.

Thin Section (, 2) Description: Gretchen Benedix, Linda Welzenbach and Tim McCoy
The sections consist of many small chondrules with some up to 1.5 mm, mineral grains and CAIs set in a black matrix; rare metal and sulfide grains are present. Olivine compositions are Fa_0-53, orthopyroxene is Fs_1-16, although the majority of orthopyroxene is less than Fs₃. The matrix consists dominantly of serpentine. The meteorites are CM2 chondrites.
