Estherville was one of the most spectacular bolides yet witnessed when it tore its way through Earth’s atmosphere above Iowa in 1879. The following papers are 1) a thorough description of the event and early description of the meteorite, and 2) a more modern take on dating the various components of the meteorite.
When this meteorite fell, thousands of small metal ‘nuggets’ ablated out of the less-durable stony matrix. This is one of those specimens. Many thanks to Anne Black for making this 4.19 gram complete individual available.
