Macroscopic Description: Kathleen McBride
The exterior is completely covered with weathered brown-black fusion crust exhibiting polygonal fractures and evaporites. The interior is a chocolate brown, soft matrix with rust and cream colored chondrules ranging in size from 1 to 3 mm.

Thin Section (,4) Description: Tim McCoy and Linda Welzenbach
The section exhibits well-defined, metal-rich chondrules up to 2 mm in diameter in a dark matrix of FeO-rich phyllosilicate and metal. Polysynthetically twinned pyroxene is abundant. Silicates are unequilibrated; olivines range from Fa1-31, with most Fa0-2, and pyroxenes from Fs1-7Wo1-5. The meteorite is probably a CR2 chondrite.
