Comments
SgFm-3, Longhouse: A series of joined cooking features, often in rows 30-40 m in length, was located near extensive communal dwellings on the site. The contemporaneity of several hearths was tested by dating samples of charred willow wood, omitting spruce wood and charred bone (GSC-2757, GSC-2834, GSC-3141). Two bone samples were sent to the Geochron lab. A separate component on this site is termed the "Early Dorset Ridge" and is dated by a sample of charred bone (GSC-3262). The bone is presumed to represent sea mammals, but the 13C ratio is unusual for any kind of bone and is far-removed from the ratio for sea mammal bones. BM-1754 is a surface find dated to establish the rate of weathering in the Arctic environment.
