Macroscopic Description: Kathleen McBride
Brown/black fusion crust covers over 50% of the exterior surface. The crust exhibits polygonal fractures and oxidation halos. The exposed interior is multiple shades of gray with some rust and exposed clasts. The interior is brecciated with a medium gray matrix with numerous multi-colored clasts, round to angular in shape and varying in size from 1-2 mm.

Thin Section (,4) Description: Tim McCoy, Linda Welzenbach
The section contains abundant basaltic clasts with rare orthopyroxene clasts. The basaltic clasts include heavily shocked coarse-grained clasts, clasts dominated by metal and sulfide and a glassy quench-textured clast, with individual clasts ranging up to 2 mm. Minerals present include olivine (Fa33), orthopyroxene (Fs33-59; Fe/Mn ~ 25), augite (up to Fs53), plagioclase (An92-95), metal and sulfide. The meteorite is a howardite.
