This is not a complete specimen. The S and T surfaces have very thin, dull patches of fusion crust. The B surface has thin, shiny black fusion crust, portions of which have weathered to reddish-brown. There are numerous inclusions, both chondrules and lithic clasts, visible through the reddish-brown oxidation rind. The largest chondrule is approximately 0.5 cm in diameter and is lighter colored than the surrounding matrix. A few inclusions that are darker than the matrix are also observed; however, they are not as numerous or as large. The sample is angular, 11.0 x 6.5 x 5.0 cm, and has many obvious fractures on the exterior surface.
