Macroscopic Description: Kathleen McBride
Brown/black fusion crust with oxidation haloes covers the entire exterior surface. The interior is a medium gray matrix with high metal and light colored, rust stained chondrules, 1-4 mm in size.

Thin Section (,2) Description: Linda Welzenbach, Tim McCoy
The section exhibits numerous, well-defined chondrules (up to 3 mm) in a black matrix of silicates, metal and troilite. Weak shock effects are present and polysynthetically twinned pyroxenes are present. The meteorite is mildly weathered. Silicates are unequilibrated; olivines range from Fa13-27, with a peak from Fa16-19, and pyroxenes from Fs2-16. The meteorite is a H3 chondrite (estimated subtype 3.7).
