Tehuacán Valley

[tey-wah-kahn, -wuh-kan]
noun
  1. a desert valley site in Puebla, Mexico, where aridity has preserved the vegetable remains of communities from 9000 b.c. to historic times, thus documenting the transition from hunting and gathering to the largely agricultural subsistence of the full Neolithic phase (1500–900 b.c.).
