Recognized 1937
A find known for many years from somewhere in southern Clark County was recognized as an iron meteorite in 1937. While heavily corroded it retains a good Widmanstätten pattern and exhibits prominent uniform Neumann bands due to preterrestrial shock. Along with Nelson County it is one of two Kentucky type IIIF medium octahedrites — a rare subclass of iron meteorites with only 9 known members. Fe-Ni metal is characterized by the distinct kamacite-plus-minor-taenite regions defining the octahedral character accompanied by scarce plessitic intergrowths. Troilite accompanied by Daubréelite and Schreibersite (along grain boundaries) are also found.
