Camp Wood        29°46’21"N, 99°52’30"W

Real County, Texas, United States

Found: 1960s

Classification: Iron meteorite (IIIAB)

History:  A single 148 kg mass was found by Guy Hutcherson in the late 1960s, while hunting with his son, Robert Hutcherson, on their property, north of Ranch Road 337 between the towns of Camp Wood and Leakey.  Noting its unusual appearance and metallic quality, they exhumed the partially buried mass and brought it home, where it remained until 2007, a presumed meteorite.  In 2007 a 28.6 gram sample was sent to NASA, forwarded to the Smithsonian and confirmed to be a meteorite.

Physical characteristics:  The mass is irregularly shaped, and measures approximately 50×48×30 cm at its widest points.  Its surface is moderately weathered and is dominated by numerous well-defined shallow depressions ranging from 5 to 20 cm in diameter that appear to be due to the effects of weathering.  No fusion crust remains.

Petrography: (J. Wasson, UCLA) No widmanstätten figures were visible on a small etched surface, but some kamacite lamellae could be recognized because the meteorite had oxidized along kamacite boundaries and some conversion of kamacite into oxide occurred. The mean bandwidth is 0.9±0.1 mm, Om. No schreibersite, troilite, or other inclusions were observed in the sample.

Geochemistry: Bulk Composition: INAA data (J. Wasson, UCLA): Co = 5.0 mg/g, Ni 74 mg/g, Cu = 154 μg/g, Ga = 18.4 μg/g, As, 3.4 μg/g, Ru = 13 μg/g, W = 1.2 μg/g, Ir = 12.1 μg/g, Pt = 15 μg/g, Au = 0.566 μg/g.

Classification: Iron meteorite, IIIAB group, medium octahedrite.

Specimens: Type specimens, 28 g, UCLA; main mass, JUtas.
