The entire exterior is covered with shiny brown/black fusion crust. The interior has a rusty, crystalline surface texture with a high metal content.

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

The section shows an aggregate of small chondrules (up to 1 mm), abundant chondrule fragments, and pyroxene grains in a heavily weathered matrix. Several chondrules contain olivine. Microprobe analyses show the, orthopyroxene is Fs0-1. The meteorite is an E3 chondrite. The complete weathering of metal makes the subtype (EH vs. EL) uncertain.
