Crow Peak                                     44°28.64N, 103°58.32W

Lawrence County, South Dakota, USA

Find: July 1958

Iron (IIAB, hexahedrite)

History: R. Meink recovered a single specimen while clearing a hay field. The specimen went to R. Meink’s nephews, W. and D. Copas, upon his passing. W. Copas sent a sample of the specimen to the Center for Meteorite Studies for classification. The Center purchased the main mass after verifying its classification.

Physical characteristics: The meteorite weighed 6320 g when found. Its fusion crust has weathered to a brown color.

Petrography: (L. Bleacher, ASU) The meteorite appears to be composed exclusively of kamacite and exhibits at least 3 sets of Neumann lines.

Geochemistry: (J. Wasson, UCLA) The composition (by INAA) of the metal is Co = 4.5, Ni = 57.2 (both mg/g); Cu=138, Ga = 57.8, As = 3.72, W = 3.4, Ir = 36.5, Au = 0.515 (all µg/g).

Classification: Iron (IIAB, hexahedrite).

Type specimen: A total of 6272 g is on deposit at ASU.
