It was occupied from about 800 CE to about 1300 CE. The site also features a 1 metre (3.3 ft) in height 30 metres (98 ft) by 35 metres (115 ft) circular feature known as the Annis Sand Mound (15 BT 21) that dates from the Archaic period. This feature lies directly north of the village area and outside of the area encompassed by the palisade.
