Sutter's Mill Meteorite Fall

On April 22, 2012, a bright fireball (bolide) was seen over parts of California and Nevada at approx. 7:51am (PDT). This fireball heralded the arrival of a mini-van sized space rock which entered the Earth's upper atmosphere over Sutter's Mill California and dropped meteorites across streets and backyards. These meteorites are now being found by professional hunters, landowners, and scientists. Listed below are the specimens that have been found and reported. There are likely more stones that have been found but not reported, so this list is not definitive. I will update this list as new information becomes available. If you know of a specimen that was found and is not on this list, please contact me via email.
