Writeup from MB 105:

Yucca 044        34°43.637’N, 114°14.738’W

Arizona, United States

Find: 14 Feb 2011

Classification: Ordinary chondrite (H4)

History: Two stone pieces that fit together totaling ~3.2 kg were found by Teri Lynn Johnson on Feb 14, 2011. On the same date and nearby, Scott Johnson found an additional 26 g stone that fit between the two larger pieces.

Petrography: Sample is composed of numerous well-defined chondrules and chondrule fragments set in a fine-grained matrix. Feldspathic material consists of a mix of devitrified glass and small (mainly <20 μm across) plagioclase feldspar grains. Numerous chromite-plagioclase assemblages and grains of native copper are present.

Geochemistry: Olivine (Fa19.9±1.0, N=46); orthopyroxene (Fs17.0±1.4Wo1.5±0.7, N=21)

Classification: Ordinary chondrite (H4)

Specimens: Cascadia holds 51.5 g in multiple pieces, in addition to one polished thin section and a mounted butt
