Cliff Palace was constructed primarily out of sandstone, mortar and wooden beams. The sandstone was shaped using harder stones, and a mortar of soil, water and ash was used to hold everything together. "Chinking" stones were placed within the mortar to fill gaps and provide stability. Many of the walls were decorated with colored earthen plasters, which were the first to erode over time.[citation needed ] Many visitors wonder about the relatively small size of the doorways at Cliff Palace; the explanation being that at the time the average man was under 5 feet 6 inches (1.68 m), while the average woman was closer to 5 feet (1.5 m).[citation needed ] Cliff Palace contains 23 kivas (round sunken rooms of ceremonial importance) and 150 rooms and had a population of approximately 100 people. One kiva, in the center of the ruin, is at a point where the entire structure is partitioned by a series of walls with no doorways or other access portals. The walls of this kiva were plastered with one color on one side and a different color on the opposing side.[5] "It is thought that Cliff Palace was a social, administrative site with high ceremonial usage."[6] Archaeologists believe that Cliff Palace contained more clans than the surrounding Mesa Verde communities. This belief stems from the higher ratio of rooms to kivas. Cliff Palace has a room-to-kiva ratio of 9 to 1. The average room-to-kiva ratio for a Mesa Verde community is 12 to 1.[1] This ratio of kivas to rooms may suggest that Cliff Palace might have been the center of a large polity that included surrounding small communities.[1]
