An ordinary chondrite (stony meteorite), high in iron (H group) and petrologic type 5.
The fall was witnessed on October 17, 1921, around 11:00 pm, near Rose City, Michigan.
The only two specimens (13 and 7 pound) recovered from this meteorite were found on George Hall’s property.
This meteorite has a unique structure, because at one point it was heated to a molten-like state, deforming the chondrules and causing the metal within it to flow, before solidifying again. This happened long before it entered Earth’s atmosphere.
