	abstract = {<p>Two sets of chronologically and culturally distinct artifact assemblages from the Western Alberta Plains are compared in terms of particular stone flaking patterns exemplified on clastic rocks (quartzite cobbles) of similar structural and mechanical properties. Although recorded in specific geo-archaeological contexts - from beneath early Late Wisconsinan glacial deposits at Calgary, and within shallow, late Holocene subsurface lake deposit along the shore of Lesser Slave Lake, respectively - both lithic collections show identical culture-diagnostic stone modification attributes. Overall similarities in the raw material procurement strategies, use, and the applied cobble-tool percussion techniques suggest an analogous, expedient character of the produced artifacts. In spite of the high-energy, post-depositional glacial and glaciolacustrine environments at the deeply buried (15-25 m) Bow Valley sites, most of the recorded artifacts manifest meticulous cobble-face flaking and edge-retouching, indicating occasionally even a higher degree of flaking control than encountered in the Middle to Late Prehistoric period site on Lesser Slave Lake. Lack of obliteration of the culture-diagnostic lithic artifact attributes suggests a very good potential for preservation of early archaeological sites in Canada in areas formerly affected by glaciation.</p>},
