Might be worth seriously checking this one out. According to the Meteoritical Society (http://www.lpi.usra.edu/meteor/index.php) index, there was a 1912 meteorite discovered near Holbrook, AZ in 1912. Some 220 kg. of material has already been recovered. For meteorites, that's pretty big.
If material found near Aztec as well, might define a strewn field with hundreds of specimens. Classified as an L/LL chrondrite, I believe.
The above website is an excellent source for anything meteorite-related anywhere in the world.
