Macroscopic Description: Kathleen McBride
Exterior is completely covered with dull black fusion crust with polygonal fractures. The interior is mostly rusty with high metal and light colored chondrules stained with rust.

Thin Section (,2) Description: Tim McCoy
The section consists of abundant small (up to 1 mm) chondrules, chondrule fragments and mineral grains in a dark matrix. Metal and sulfide occur within and rimming the chondrules. Olivine ranges in composition from Fa1-55, with a continuous range of intermediate compositions and a slight peak at Fa0-2. A single pyroxene is Fs1. The meteorite is a CO3 chondrite, probably of relatively low petrologic type.
