The buried gorge leading from the Whirlpool is bounded by compact limestones with their faces steep, except where these are rounded and glaciated, with striations along the direction of its course. In breadth the ancient and now buried gorge increases from 1,400 feet at the Whirlpool to 1,800 feet in a distance of 2y2 miles. Having discovered in this gorge, at a depth of 186 feet, the remains of a buried interglacial forest, its glacial history is the theme of this paper. As shown by Professor Coleman, the first announcement of the occurrence of interglacial beds in Canada was made by my friend, the late Mr. D. F. H. Wilkins.
