The Timbisha Shoshone Story ...

The Shoshone are part of a great language phylum known to linguists as Aztec-Tanoan. Evidence indicates Aztec-Tanoans were probably a component of the hunter/gatherer Cochise Culture of southwestern New Mexico, southeastern Arizona, and northern Mexico. This culture began about 10,000 years ago, and lasted to about 500 B.C. But since this period began about the time of the end of the last Ice Age, flora and fauna were becoming sparse and even extinct and many tribes, including the Uto-Aztecan ancestors of the Shoshone, apparently fissioned about that time from this Cochise Culture.
