The Oliver Phase people built a village at what is now Strawtown Koteewi Park, and the site, dated to A.D. 1200-1450, is thought to represent the beginnings of the Oliver Phase peoples. Archaeological evidence indicates that approximately 150 people lived there during its most active period, growing maize and occupying the village throughout the year. Also known as the Strawtown Enclosure, it is the earliest known Oliver Phase site identified to date. The 100-yard circular village was enclosed by a wooden stockade wall and an earthen embankment. Evidence also shows deep storage pits and a designated area for food storage, with houses placed along the inside perimeter of the stockade wall and the center reserved for communal activities.
