The Gold Basin meteorite was unwittingly discovered (and discarded) by gold prospectors in the "Gold Basin" area of the Arizona desert. Hunters looking for gold nuggets would find "hot rocks" that would set off their metal detectors. Upon seeing these unremarkable rocks were not gold, they would toss them aside. Later, Professor Jim Kriegh recognized these rocks as meteorites and had them classified. He then spent many years mapping out the strewnfield of this ancient fall and his name is forever associated with this meteorite.
Gold Basin is an attractive L4 chondrite that has a matrix filled with chondrules and metal flecks. It is considered a classic American meteorite find with a well-documented body of science around it.
