An open area in the pueblo near the rim of the earthcrack served as the plaza, the center of many daily activities including grinding corn, making pottery, working obsidian into arrowheads, processing other plants for food, and cooking. It was also used for meetings, conducting trade, and as a controlled play area for children. During the warmer months, the plaza was used extensively from dawn until after dusk, while rooms inside the pueblo were used only for sleeping and some cooking. At the bottom of the earthcrack, a prehistoric check dam contained frequent run-off, and the inhabitants of the pueblo also placed numerous pottery jars at the base of overhangs to catch rainwater. When rain did not come, they had to walk ten miles to the Little Colorado River drainage to fill their pottery jars.
