EARTH'S SHIFTING CRUST
2. Weakness of the Accepted Glacial Chronology
Geologists are used to thinking of four major glaciations
during the million-year period of the Pleistocene. They have
assumed that each glaciation
affected the earth as a whole
simultaneously, causing ice sheets in both Northern and
Southern Hemispheres, and lowered temperatures generally.
Some geologists have questioned this concept of four glaciations;
it is at least necessary to recognize several successive
phases of advance and retreat for the older glaciations.
Whether these interruptions were merely interstadials, like
those of the Wisconsin glaciation, or were true interglacials
it is increasingly hard to decide the further back in time one
goes. According to the accompanying chart of the glacial
periods (p. 282), it is evident that the intervals between the
different stages of the major glacial periods are in some cases
longer than the entire duration of the Wisconsin glaciation.
It does not seem reasonable, therefore, to insist that they
were merely interstadials, nor, consequently, to insist upon
the number of just four glaciations during the Pleistocene.
This becomes more apparent when we consider the implications
of the Eurasian continental glaciation mentioned
above. This, obviously, makes at least a fifth Pleistocene
glaciation, but the matter does not end there. The question
must be asked, If European geologists could overlook the
evidences of this comparatively recent glaciation until the
last decade (and this in spite of the fact that the evidences
were spread widely over two continents, and had attracted
the attention of Russian geologists as long as seventy-five
years ago), how many other glaciations in various parts of
the world may not have escaped attention? Flint has pointed
out how easily glacial evidence can be destroyed (342:171),
Coleman also emphasized the same thing:
It might be supposed that so important a change would leave be-
hind it evidence that no one could dispute, and that there should be
no room for doubt as to what happened in so recent a time of the
