| Macroscopic Description - Kathleen McBride |
| 75% of the exterior is covered with black shiny, ropey fusion crust. The exposed interior is gray with numerous vugs. Some areas of fusion crust exhibit polygonal fracturing. The interior consists of tan clasts of various sizes surrounded by light gray matrix. Some areas have white material (evaporites). The fine grained matrix is soft and moderately friable. |

(,6) Description - Tim McCoy, Linda Welzenbach, Cari Corrigan, and Rhiannon Mayne |
| This meteorite is dominated by fine-grained (~200 micron average grain size) basaltic clasts set in a clastic matrix. Mineral compositions are homogeneous with orthopyroxene (Fs62Wo2), with lamellae of augite (Fs27Wo43), and plagioclase (An88Or0.4). The Fe/Mn ratio of the pyroxene is ~30. The meteorite is a brecciated eucrite. |
