Macroscopic Description: Kathleen McBride
The exterior has striated brown/black fusion crust with oxidation haloes. Some thin fractures and pits are visible. The interior is black matrix with rust-colored chondrules. Evaporites are visible along fractures. The meteorite is hard.

Thin Section (, 2) Description: Gretchen Benedix, Linda Welzenbach and Tim McCoy
The section exhibits numerous small, well-defined chondrules (up to 1.5 mm) in a black matrix of fine-grained silicates, metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is extremely abundant. The meteorite is relatively weathered. Silicates are unequilibrated; olivines range from Fa_2-19. Orthopyroxene is Fs₇. The meteorite is an H3 chondrite (estimated subtype ~3.5).
