The Cajon Group (pronounced ca-hone) consists of a small village constructed in the same configuration as Hackberry, Horseshoe and Holly. The surviving structures are situated at the head of a small canyon, and evidence indicates that 80 to 100 people may have lived here. Under a ledge are several small structures as well as pictographs painted in the Mesa Verde pottery style. In the canyon below, the remains of an earthen dam built to store water can still be seen today. On the western slope of the canyon stand the remains of a remarkable circular tower (shown in photo above) that conforms perfectly to the shape of three large, irregular boulders. This round structure on a completely uneven surface demonstrates the skill and determination of the ancestral Puebloans that lived at Hovenweep.
