Macroscopic Description: Kathleen McBride
100% of the exterior is covered with dull, brown/black fusion crust with oxidation haloes. The chocolate brown interior has millimeter sized multicolored chondrules.

Thin Section (,2) Description: Tim McCoy, Cari Corrigan
The section exhibits large (up to 2 mm), well-defined, metal-rich chondrules and CAI's in a dark matrix of FeO-rich phyllosilicate. Polysynthetically twinned pyroxene is abundant. Silicates are unequilibrated; olivines range from Fa0-5, and pyroxenes from Fs1-3. The meteorite is probably a CR2 chondrite.
