Observed fall September 28, 1969
Caronaceous Chondrite CM2, 12g
This meteorite contains 230 amino acids of extraterrestrial origin. Some feel it is of cometary origin, but it is a close spectral match for the asteroid 19 Fortuna.

Achondrite, Howardite 14g
Howardites likely represent the regolith of the asteroid Vesta. These polymict breccias are thought to be formed by the mixing of eucrite crust with the upper mantle diogenite rocks by large impacts.

H/L3-4, 14g
This rare meteorite is currently the only one in the world classified as an H/L3-4. It is a breccia composed of fragments of both type 3 and type 4 material and the chemistry (iron content of the olivine and pyroxine, etc.), which usually gives a distinct grouping, was odd enough to not give a certain H or L typing to this strange specimen.

Primitive achondrite, Lodranite, 4.6g
This was originally classified as an acapulcoite (and still is by the Meteoritical Bulletin Database). Both acapulcoites and lodranites come from the same parent body and are chemically and isotopically indistinguishable. Their only difference is in their average crystal grain size; acapulcoites less than 0.3mm and lodranites greater than 0.45mm. This stone has an average grain size of 0.6 to 0.7mm. The researchers who originally classified this rare stone mistakenly thought that the lodranite cutoff was 0.75mm when they submitted the original classification paper work on this meteorite.
