original depression of its surface, now filled with ninety feet of 
stratified clay, very like the lower beds, but more calcareous and 
apparently free from fossils and concretions. 
At the point where the upper terrace comes out to the shore 
these stratihed clays are covered conformably by a series of 
stratified sands with some clay beds, in all seventy feet thick. 
Several of these beds at different levels are remarkably crumpled 
and contorted, while the beds immediately above and below 
appear quite undisturbed. They have perhaps been folded by

examples figured in Gezkie’s Great Ice Age No fossils have 
been obtained from these inter-glacial beds. 
The upper till, which overlies the country to the north of the 
Scarboro’ Heights, forming a gently rolling table-land, described 
by Professor Chamberlin in conversation as a mild form of moraine, 
is seen at this section to consist of yellowish-brown clay with 
well striated pebbles and larger stones, fragments of black Utica 
shales, often falling to pieces, limestones apparently of Trenton 
age, and archean rocks, such as gneisses. It differs from the 
lower till in being somewhat more sandy, and especially in hav-
