[AMI] SYNOPSIS OF THE GEOLOGY OF CANADA 225 
St. Maurice and Sorel sands, etc., are as many geological horizons and 
formations which enter into the nomenclature of the Pleistocene of 
eastern Canada. 
The Interior Continental Plain.—In Manitoba, lake beaches and 
delta deposits characterize the recent pleistocene period. The Champlain 
period is represented in this province by the beaches and deltas of Lake 
Agassiz, associated with terraces and valleys. During the glacial period 
in Manitoba, till, moraine, drumlins and kames in the valleys occur 
throughout, whilst on the Rolling river may be seen clays and sands 
possibly referable to inter-glacial or pre-glacial times. 
Tur RECENT PERIOD. 
It was not until after the close of the Champlain period in Canada, 
that man made his appearance. A period of elevation followed the 
period of submergence. On the north shores of Lake Erie, remains 
of the mastodon and the mammoth, which were the elephants 
of the New World, indicate their presence immediately after the close of 
the glacial period. The remains of deserted villages of the aborigines of 
British North America, characterizing the various strides of the 
American race, their graves, or burial places, have been found, together 
with their stone or copper implements, in all our provinces and only in 
the most recent of our superficial deposits, whilst with these imple- 
ments, are found associated remains of beaver, deer, bear and other 
animals of the chase identical with those of to-day.
