Today’s picture comes from the Ahai Mneh site on the shores of Lake Wabamun, west of Edmonton, AB. This archaeological site has a long history of human occupation, from earliest hints of people in Alberta using Clovis technology, right up to the Late Precontact and Historic Periods. Featured here is a large radial biface, made of a fine-grained siltstone. This artifact was found in a field adjacent to the site, having been turned up by a plow. While not exclusive, radial bifaces such as this one are commonly associated with the Clovis tool kit, dating back to 13 000 years ago in Alberta.
