Macroscopic Description - Kathleen McBride
95% of the exterior is covered with smooth dark brown fusion crust. The interior matrix is rusty. The meteorite has a high metal content and is hard and brittle.
Thin Section Description (,2) - Cari Corrigan and Nicole Lunning
This meteorite section consists of equigranular crystals (up to 0.5 mm) of polysynthetically twinned enstatite, feldspar, iron-nickel metal, and sulfides. Texturally, this meteorite is similar to Happy Canyon. Microprobe analyses show pyroxene compositions of Fs0-1Wo1. This meteorite is an enstatite chondrite impact melt and is likely paired with MIL 090807.
