The older interpretations of the Pleistocene history of New York and New Jersey have been made upon what seems to be the tacit assumption that sea level remained stationary while the land rose and sank. It has become clear, and has been pointed out by numerous writers of recent years, that the first part of this assumption is untenable, for the accumulation of continental ice sheets must have withdrawn enough water from the oceans to have appreciably lowered sea level. Estimates of this lowering have been made, ranging from a few score to more than 300 feet; the most recent and careful one being that of Antevs,1 as 262–305 feet. Daly,2 for purposes of discussion, uses 262 feet as a conservative figure of the lowering at the maximum of the last glaciation. Roughly, the same amount of lowering would have taken place at the maximum of the three . . .
