Between 1300 and 1450 AD Pueblo culture thrived in what is today Southeast Arizona and Southwest New Mexico. While decidedly Pueblo in origin this culture was also distinct from Western Pueblo and Eastern Pueblo culture, it was a separate and unique "Southern Pueblo" tradition. Around 1450 something terrible happened and these villages were abandoned across the entire region. And while the descendants of Western Pueblo culture can be found at Hopi and Zuni pueblos and Eastern Pueblo culture's heirs are the New Mexico pueblos along the Rio Grande and Rio Puerco Rivers, the descendants of the Southern Pueblos are nowhere to be found. Join me as I track down the remains of this once great and seldom studied civilization, help me to answer the big questions. Who were they? Where did they go? What happened?
