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 in the canyon below are several small structures that may have been built to protect and store water from the spring. 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.
