Identified in the course of the 1993 Birchtown Archaeological Survey, AkDi-30 is an architecturally complex site, much like AkDi-11. This site was mapped during the 1999 field project. It is roughly 180 metres square and features a long "run" (65 metres) comprised of two parallel walls about two metres apart, each wall about a metre wide. The small three-sided stone structure, about 3 x 5 metres with an opening facing south, was shovel tested in 1993. No artifacts were retrieved, but a large pine tree growing on top of one of the walls was dated (using the tree-ring method) and suggests the walls were constructed by the early nineteenth century. This indeterminate site may prove, with further archaeological testing, to be one of the homesteads built by the original Black Loyalist settlers. Birchtown's rock walls are a significant part of the Black Loyalist cultural landscape and may hold a key to understanding historic Birchtown.
