The paper on the Late Archaic wall trench structure from the Davidson site (Ellis and Keron 2011) discusses a similar structure from the Rock Hearth site in Berrien County, Michigan. I was unaware of the structure until reading about it in the Davidson paper. Chris Ellis was kind enough to make available sections of the original report (Garland et al.1990), from which the figure at the right is taken. Two radiocarbon estimates place the age of the structure at around 3700 BP. I have added the reference to the Bibliography section, and the structure will be included in the next issue of the Database.
