As you walk from No. 10 to 11, you will pass several potholes that become pools of water after a rain. Some of these were artificially enlarged by the Indians who lived on the mesa top, to serve as supplementary sources of water.

The dark color here is caused by carbonized remains from the plants which grew in the ancient swamps. Coal is formed in much the same way, but there is too much inorganic material in this seam to produce coal. This is the coal-like seam mentioned at [No. 7]. On the very top, the dirt is from the Mancos formation of Cretaceous age, and is composed of marine shales deposited in the ancient sea which covered the area. It was originally much thicker, and is younger than any of the other rocks exposed here.
Immediately ahead and extending to the right for nearly 300 feet is the ruin called Atsinna, a Zuñi word referring to the “writing on rock.”

Atsinna, the larger of the two ruins, is approximately 200 by 300 feet, the size of some city blocks. Like the other village, parts of it probably were three stories high, mainly along the north side. It was terraced down toward the south, thus providing a southern exposure. You are standing on the second floor level about ten feet above the original ground level. The first floor was filled with debris from the collapse of the upper stories.
The Indians obtained most of their water from the pool at the base of the rock, as did the later Spanish and American travelers, but they also caught as much water as they could on the mesa top.

This round room, is called a kiva. Kivas were built primarily for religious ceremonial reasons, but had other purposes, just as the large halls in cities today are used for exhibits, concerts, lectures, and other activities. In addition to religion, these rooms were used for workrooms, playrooms, general meeting places, fraternal society meetings, etc.
