Macroscopic Description - Cecilia Satterwhite
The exterior has fractured brown/black fusion crust with evaporites. Flow lines are visible on one surface. Areas without fusion crust are weathered brown with some gray/black matrix visible. Some rusty areas are visible. The interior is a dark gray to black matrix with heavy oxidation and rusty areas. Metal is visible and this ureilite was very difficult to break.
