Macroscopic Description: Kathleen McBride
50% of the exterior is covered with a patchy brown-black fusion crust with polygonal fractures. The exposed interior is tan to yellow-orange (or Dijon mustard) in color. There are several penetrating fractures. The rock seems to be rather lightweight in comparison to its size. The cream colored interior matrix has black crystalline clasts (< 1 mm) which make up the most numerous components of this meteorite. Less frequently occurring inclusions are transparent subhedral clasts and elongated, flat grains of a light brown color. This meteorite appears to be weathered and friable except on the most interior areas away from fractures.

Thin Section (,2) Description: Tim McCoy and Linda Welzenbach

Plane-Polarized Light	Cross-Polarized Light

The section exhibits coarse (>5 mm) individual pyroxene grains, polycrystalline fragments and comminuted groundmass grain of uniform composition of Fs₂₆Wo_1-2. The Fe/Mn ratio of the pyroxene is ~30. Small diopside grains were noted optically, as were metal, sulfide and mm-sized chromite grains. The meteorite is a diogenite.
