Macroscopic Description: Kathleen McBride
100% of the exterior is covered with brown/black fusion crust. Some fractures and oxidation haloes are visible. The interior is a black and rust colored matrix with a high metal content. The matrix contains light colored clasts. Some of these clasts are stained with rust. Their sizes ranges from 2 mm - 1 cm in diameter.
