Eighty percent of this ureilite is covered with fusion crust which is smooth and black on the top and frothy on the bottom. The interior is black with areas of oxidation. Metal and white to yellowish colored mineral grains are visible on the interior and many larger interior grains have obvious cleavage planes. The specimen was very coherent.

Individual grains are rimmed with carbonaceous material which contains trace amounts of nickel-iron and troilite. The meteorite appears to be relatively unshocked. Microprobe analyses show the following compositions: olivine, Fa22; pyroxene, Wo11Fs18. The meteorite is a ureilite.
