Macroscopic Description: Kathleen McBride
This meteorite is shaped like a volcanic bomb and has a rusty-colored, exfoliating, flaky exterior. It is dull on one side and shiny on the opposite side. Thick evaporitic material is present on two exterior surfaces. The flaky crust has numerous surface cracks that do not penetrate the interior and run mostly in the longitudinal direction. The weathered crust extends a few millimeters into the interior. The interior is very fresh compared to the exterior and proved to be very coherent and extremely hard. The interior is fine-grained and varies in color from steel-gray to black with interstitial white to clear crystals.

Thin Section (,6) Description: Brian Mason
Only vague traces of chondritic structure are visible in the thin section, which shows the meteorite to consist largely of granular to prismatic enstatite (grain size 0.1-0.2 mm), about 20% nickel-iron, minor amounts of sulfides, and a little plagioclase. The enstatite is almost pure MgSiO3 (Fe 0.1-0.6%, Ca 0.7-0.9%). The metal contains 0.9% Si. One grain of plagioclase, An17, was analyzed. The meteorite is an E6 chondrite.
