Though Chaco declined as a regional religious center during the early 1100s, the same architecture spread to the Mesa Verde area. But by the mid 1200s, a different style was also taking hold, with plazas and kivas that were uncovered like amphitheaters—hints, perhaps, of a new openness. At some sites, serving bowls became larger and were frequently decorated with designs, as though intended for a ritual communion. If the pueblo people had left a written history perhaps we would read of the Anasazi equivalent of the Protestant reformation.
Some inhabitants left the relatively lush climes of what is now southern Colorado for the bone dry Hopi mesas.
