The first indication that man was present in Canada well before the final retreat of glacial ice was found at the village of Sheguiandah, on Manitoulin Island, Ontario, in the early 1950s. This paper summarizes the relevant evidence and arguments. The key deposits are two thin layers of diamicton toward the top of the glacial sequence, immediately below a post-glacial level characterized by Paleo-lndian projectile points. The unsorted mixtures of clay, sand and stones contain undisputed quartzite artifacts. These diamictons are considered to be till; alternatives, such as mixing by frost action and mud flows, do not explain their origin. The means by which the artifacts survived the Laurentide glaciation are suggested by the orientation and...
