Ever since the general acceptance of the theory that Bering Strait served as the entrance of man into North America, Alaska has been suggested as the most likely area for additional discoveries adding to our knowledge of Early Man. In spite of the fact that the bulk of these discoveries has occurred in the Southwest or in the far west of the United States proper, increasing attention has been paid to northern regions. The Folsom and also the Yuma problem (or problems as the case might be) have been traced into the northern Plains regions of Saskatchewan, Canada.
