[4] Named for its type site at Princess Point near modern-day Hamilton, Ontario, Canada, the complex was present in the area between the Grand River and the Niagara Peninsula.
Stothers describes Princess Point maize cultivation as "developmental-experimental",[4] and notes the appearance of palisaded agricultural villages containing proto-longhouses.
By the end phase of this Grand River focus, however, occupation had shifted away from river-adjacent floodplains to well-drained sandy hills and plains in modern-day Norfolk County, which were more suitable for maize agriculture.
[8] Later accelerator mass spectrometry (AMS) testing done in the mid-1990s on samples from the Grand Banks site (AfGx-3) returned a calibrated radiocarbon date of AD 540.
[9] Stothers divided the Princess Point complex into a set of three regional foci composed of clusters of similar sites.
