Scientific data affirming the Genesis account of a global flood have been increasing in recent years. There is likewise evidence for a serious reappraisal of the classic views on glaciation in the Northern Hemispheres. There is the need to reconsider the earlier and older views of the monoglacologists. Such views are quite favorable to the concept of a world wide deluge. The Ice Age, scientifically termed Pleistocene or Quarternary, was the last geological epoch and the most carefully studied time of continental glaciation. Its express nature, causes, and duration are crucial factors for postulating one or several glaciations, and for the evidence supporting the global flood. Although monoglacialogists postulate continental ice caps, the ice caps are thought to have been much smaller in extent and to have been accompanied by marine transgression, floating ice and other fluvatile elements. Like polyglaciologists, monoglaciologists adhere to the belief that the ice disappeared about 8-10,000 years ago. But unlike polyglaciologists, monoglaciologists hold to a drastically shorter period of glaciation. This paper will deal primarily with the pleistocene period of time. The weaknesses of classic polyglaciology and the increasing plausibility of once discarded monoglaciology will be considered in detail. The conduciveness of the theory of monoglaciology to the Biblical revelation of a world wide flood will be shown.
