Grace Rajnovich's (1983) thesis describes excavation of two Selkirk (Late Woodland) habitation structures at the Spruce Point site (DjKq-1) in the Kenora District of western Ontario. The structures were defined by a color and texture contrast between the interior and exterior sediments. Both had interior features. Neither structure was completely exposed. Rajnovich provided inferred outlines of the structures. She estimated their dimensions to have been about 4m in width x 6 or 7m in length. The plan view of Structure A is shown to the right. The plan view of Structure B is here.
Above: Structure A (from Figure 8 of Rajnovich 1983:98). This will be Structure 2235 in the database.
The Reid and Rajnovich (1991) paper contains pointers to publications with data on several Woodland and Archaic structures in the region. I've never been there, but based on its entry in Large Canadian Roadside Attractions it looks like a nice place to visit.
