Macroscopic Description: Kathleen McBride
The exterior is covered completely with brown thick fusion crust and polygonal fractures. The interior is black with an oxidation rind and rusty haloes. Some dark chondrules are visible.

Thin Section (,2) Description: Tim McCoy and Linda Welzenbach
The section exhibits medium, well-defined, metal-rich chondrules and CAIs in a dark, altered matrix that is particularly abundant. The section shows a prominent flattening and alignment, probably from shock. Silicates are unequilibrated; olivines range from Fa1-3 and pyroxenes from Fs1-6Wo1. The meteorite is a CR2 chondrite.
