Abstract

A geophysical survey was carried out during the summer of 2004 on a late prehistoric site in the eastern Quebec region of Bas-Saint-Laurent. The site, CjEd-5, dates to the Middle and Late Ceramic (Woodland) period and contains several stratified occupations within fine alluvial sediments. We carried out the magnetometer survey using a Bartington Grad 601 fluxgate gradiometer at closely spaced intervals of 1 metre. This poster presents the results of the survey and compares these to subsequent excavations that served as a 'ground truth' of the non-invasive geophysical investigation. The results were overwhelmingly positive and allowed us to save valuable time and resources by concentrating our excavations on features that were most likely to provide radiocarbon dates and close associations of artifact classes such as faunal remains and lithics.
