Writeup from MB 106:

Monteview        44°01’1.92"N, 112°29’6"W

Idaho, United States

Find: 2014 Oct 13

Classification: Iron meteorite (IAB-MG)

History: Found October 13, 2014 by Matt Bird on a fence line in an agricultural area, about 6.4 km from the town of Monteview, Idaho.

Physical characteristics: The specimen has a mass of roughly 25.9 kg with well-developed regmaglypts and subspherical surface cavities. Surfaces are mostly rusty but have a metallic appearance in places.

Petrography: (A. Ruzicka, Cascadia): Etched and polished cut surfaces show that sample largely consists of kamacite crystals in a Widmanstatten pattern. Elongate crystals of cohenite up to 0.5 cm long parallel the kamacite plates. Small amounts of zoned taenite, plessite, schreibersite, and weathering products are present. Texture and mineralogy resembles cohenite-rich pieces of the Wichita County coarse octahedrite.

Geochemistry: (G. Chen, C. Herd, UAb): trace elements in μg/g except where noted: Co 4.89 mg/g, Ni 70.6 mg/g, Cu 156, Ga 102, Ge 454, Ru 6.17, Rh 1.49, Pd 3.17, W 0.99, Re 0.20, Os 0.72, Ir 2.12, Pt 6.82, Au 1.49.

Classification: (A. Ruzicka, Cascadia): IAB main group based on trace element composition; somewhat higher in Ga, Ge and Co and lower in W, Re and Ir than other IAB main group irons including Wichita County, Odessa (iron), Canyon Diablo, and Campo del Cielo.

Specimens: Cascadia holds 173.6 g in four pieces as well as a large vial of rusty surface fragments. The main mass is held by the family of Matt and Michelle Bird.
