Publisher's Synopsis
Excerpt from Late Pleistocene Oscillations of Sea-Level in the Ottawa Valley
No marine sediments are known to be overlain by glacial till in the Ottawa valley and no deposits which might be regarded as interglacial are known to occur. It is possible that the region was invaded by ice-sheets during early stages of Pleistocene glaciation; but. If so, no definite records have been left, so far as is known. It is probable that the glacial deposits in the region all belong to the latest. Or Wisconsin stage of glaciation.
