"It was during the Festival of the Drum, the Corn and the Squash that Guerra learned there were no longer abundant deer in the Huichol parts of the Sierra Madre because of settler encroachment and overhunting by poachers. Because deer are central to the Huichol cosmology and ceremonial cycle, as depicted in the work of Huichol artist Marcos García López below, Guerra gave thought to the daunting practicalities of doing something about the situation. He dreamed of bringing the deer back."
