Cuspate Forelands along the Bay of Quinte

Abstract

THE flat-lying limestone regions immediately to the north and east of the east end of Lake Ontario are traversed by a number of deep valleys with graded side slopes on their lower courses. These valleys are probably of preglacial origin, and were carved at a time when the relative altitude of the several parts of the Ontario lowland was different from what it is at present. The partial submergence of a number of these valleys, tributary to one another, has formed the water body known as the Bay of Quinte. This bay extends from near Kingston, at the east end of Lake Ontario, toward the southwest for a distance of over fifty miles, and nowhere has it a breadth exceeding two miles. A reference to the accompanying general map will show its remarkable zigzag course., For purposes of study it may be
