The Kiva

This is photograph of a kiva, which is a subterranean room apparently used by the ancient Pueblo peoples for religious and ceremonial, and perhaps for other communal purposes. Some of these rooms are huge, as large as 100 feet in diameter in some cases. And they had roofs covering them. They would erect stone pillars, and then large logs, then smaller logs and eventually the structure was covered with earth. I am guessing that the depth may be as deep at 20 feet. They are impressive structures when you see them in person. Most of the pueblos have a number of Kivas in them, some are much smaller than this.
