Macroscopic Description: Cecilia Satterwhite
The exterior has brown/black patchy fusion crust, shiny in areas, with some oxidation present. The interior is a brown/black, fine-grained matrix with some rusty areas and metal visible.

Thin Section (, 2) Description: Tim McCoy, Linda Welzenbach, and Gretchen Benedix
The section shows an aggregate of chondrules (up to 2 mm), chondrule fragments, and pyroxene grains in a matrix that has experienced extensive terrestrial weathering. Olivine is present in several chondrules, occasionally comprising a significant fraction of the chondrule. Olivine is Fa0-1 and pyroxene is Fs0-2. The meteorite is a type 3 enstatite chondrite, probably an EH3.
