Two hundred feet southeast of the Casamero great house lies an unexcavated great kiva, another Chacoan attribute. Appearing today as a large shallow depression in the ground, its diameter is conservatively estimated at seventy feet. This is almost twice the size of the great kiva at Aztec Ruins and even larger than the famous one at Casa Rinconada in Chaco Canyon. Its size suggests how populous this area once was.
To the east, Casamero was linked to another Chacoan outlier (not open to the public) by a road, and another road headed west from a point south of the great kiva. These features are nearly impossible to recognize from ground level. Archeaologists have been seriously studying and mapping Chacoan roads for about twenty years, and as more information has emerged, theories regarding their purpose have changed. Today, some scholars regard them as a type of ceremonial landscape expressing a belief system and manifesting Chacoan authority. They probably also served as routes for ritual processions.
