It is an L5 brecciated meteorite. Published by the Iowa Historical Society. Suddenly, without a moment's warning, there appeared in the southern sky a bright light from which emerged a great ball of fire. The meteor produced a large shower of stones near the town of Amana Iowa. Over one hundred stones were found, totaling in the vicinity of 300 kilograms.
Homestead is a very nice meteorite, and a famous fall, one of the largest in American history.
It is a crucial addition to any serious meteorite collection. It is a hard meteorite to acquire however, since most pieces were distributed to museums long ago where they remain in large collections. This was my collection piece, until I managed to trade a large piece from a famous museum. I cut up this piece to offer it to collectors.
