The glaciation over southeastern Sadonaut Island is attributed 
to a great glacier which swept over it from north to south, a gla- 
cier that filled the Strait of Georgia, with a breadth in some 
places of more than 50 miles he fiords of the northern part of 
the Strait of Georgia, and to the north, kink ice-action to a height 
exceeding 3,000 feet. In the interior, scratches were observed on
