Macroscopic Description: Kathleen McBride
40% of the exterior has thick brown/black fusion crust with polygonal fractures. The exposed interior is weathered brown and friable, appearing like rounded lumps. The interior reveals a dark gray matrix with angular, interlocking mineral grains with rounded lighter gray inclusions. Small rust haloes and fractures are visible.

The section consists of an aggregate of large olivine and pyroxene grains up to 2 mm across. Individual olivine grains are rimmed by carbon-rich material containing traces of metal. Shock effects in olivine are minor; pyroxenes exhibit mosaicism. Olivine has cores of Fa25, with rims reduced to Fa10. Pigeonite is Fs14-20,Wo8-10. The meteorite is a ureilite.
