Macroscopic Description: Kathleen McBride
The exterior of this flat, ordinary chondrite's surface is smooth and has a brown/black fusion crust with little dings and pits. This meteorite is very hard and dense. The interior is rusty and has a high concentration of metal.

Thin Section (, 2) Description: Tim McCoy and Linda Welzenbach
The section exhibits numerous well-defined chondrules (up to 2 mm) in a matrix of fine-grained silicates, metal and troilite. Moderate shock effects are present and weathering is extensive. Silicates are unequilibrated; olivines range from Fa_14-37, with a weak peak at Fa_21-25. Orthopyroxene range from Fs_10-22. The meteorite is an L3 chondrite (estimated subtype 3.6).
