They were also cannibals, devouring each other as well as the Tarahumares.

The Cocoyomes lived in caves on the high cliffs of the sierra, and in the afternoon came down, like deer, to drink in the rivers.

As they had no axes of iron they could not cut any large trees, and were unable to clear much land for the planting of corn.

They could only burn the grass in the arroyos in order to get the fields ready.

Long ago, when the Cocoyomes were very bad, the sun came down to the earth and burned nearly all of them; only a few escaped into the big caves.
Here in Zapuri the Cocoyomes had four large caves inside of which they had built square houses of very hard adobe; in one of the caves they had a spring.
