Legendary meteorite hunter, Jim Kreigh, discovered this strewn field while hunting for gold nuggets. For two years, Kreigh hunted and mapped the strewnfield in secrecy with trusted confidants Twink Monrad and John Blennert, generating what is perhaps the best strewnfield map in American history. Even though the fall has been dated from 15,000 - 20,000 years ago -- the oldest non-Antarctic distribution ellipse on our planet -- the material is in a wonderful state of preservation due to Arizona's arid climate in this elevated plateau region. All meteorites found in this location are known as Gold Basin specimens, even though recovered meteorites obviously originated in multiple fall events. That said, I'm rather certain these specimens come from the larger L4 classification.
