 The earliest of the ruins located on the property (with the exception of the irrigation canal), a "pithouse" in the traditional Hohokam style, dates to about 1050 CE.More than 50 countable "rooms" are found inside the park boundaries; it is likely that some were used for purposes other than living space, including food storage and religious ceremonies.The Sinagua people, and possibly earlier cultures, intensively farmed the land surrounding the Well using its constant outflow as a reliable source of irrigation.
