Fieldwork undertaken by the Museum of Ontario Archaeology in the 1980s and 1990s documented a range of smaller sites in north London and along the Medway River dating to the same time as the Lawson site was occupied. They include three found less than two kilometres from Lawson, as shown on this map. The Lawson site is a fortified 16th century Indigenous site located at the confluence of Medway River and Snake Creek. The site has been known to archaeologists since the mid-1800s and is now an Ontario designated heritage site and part of the Museum of Ontario Archaeology’s grounds.
