Kivas are thought to have had important ceremonial and public gathering uses. There is a Great Kiva in the middle of the plaza but you can only see a depression.
At the back east corner of the trail there is a carved stairway into the sandstone cliff. On the mesa above are other building sites and roads connecting Chaco to outlying sites as much as 100 miles or more away.
Many of the structures in Chaco show signs of planning, such as walls thick at the bottom and tapering thinner as they rise. I thought this section looked the opposite, getting thicker as it got higher.
In these two story sections the holes where large logs that formed the ceilings and floors sometimes still have remains of the logs, which would have to have been carried here by hand from 40-60 miles away.
A row of smaller logs was placed on top of the large logs to form a mesh, which was filled in with more plant material then plastered over.
The trail passes through the plaza in front of the main room blocks. In the middle of the blocks, sticking out into the plaza a little is an above ground kiva, a square enclosure with a round interior.
