Macroscopic Description - Kellye Pando, Cecilia Satterwhite

85% black shiny fusion crust on the exterior with some pitted areas; some of the fusion crust is glassy texture; exposed interior is tannish gray with light/dark and weathered minerals visible; the interior is a light gray matrix with abundant light/dark minerals visible and minor oxidation.

Thin Section Description (,2) - Cari Corrigan, Tim McCoy

These two sections consist of a comminuted matrix of mineral fragments up to 1 mm in size, with clasts including coarse ophitic and medium grained granoblastic textures. Clasts reach up to 5 mm in maximum dimension. Pyroxenes are Fs_21-63Wo_2-44 and feldspars are An_86-89Or₁. The meteorites are similar enough that one description suffices, and are both howardites.
