Macroscopic Description: Tim McCoy
These two masses each exhibit a highly corroded and discolored surface, where they were in contact with the soil on Derrick Peak, and a shiny brown surface. The upper surface is highly pitted. The larger of the two masses exhibits prominent linear protrusions of resistant schreibersite crystals in depressions formed by severe terrestrial weathering and removal of the original surface. These depressions are aligned, probably reflecting alignment of the resistant schreibersite.

Microscopic Description: Tim McCoy
On a cut surface, these are typical members of the Derrick Peak iron shower (Clarke, Meteoritics 17, 129). Only a thin layer of corrosion is found on the surface and neither fusion crust nor heat-altered zone is found. Structurally, they are coarsest octahedrites with large areas of swathing kamacite enclosing elongate, skeletal schreibersite crystals and cm-sized round troilite inclusions. Like other Derrick Peak irons, they are certainly members of group IIAB.
