The Earth's Shifting Crust by Charles Hapgood - wire of information

VII : NORTH
AMERICA AT THE POLE
In the preceding chapters much evidence has been presented
to support the contention that the earth's crust has often
been displaced. Perhaps the reader will feel that the general
evidence is sufficient. It remains, nonetheless, to show be-
yond a reasonable doubt that such a movement actually did
occur in one specific instance. I have already suggested that
the last movement may have been the immediate cause of
the end of the last ice age in North America and in Europe.
In this chapter I will review the evidence for this. At the
same time, I will try to show why the circumstances of
the displacement themselves indicate and, in fact, require the
further conclusion that the icecap in North America must
itself have been the agent of the displacement.
/. The Polar Icecap
Several independent lines of evidence, each individually ex-
tremely impressive, unite to suggest that the Hudson Bay
region lay at the North Pole during the so-called Wisconsin
glaciation.
The first line of evidence is based on the shape, and on
the peculiar geographical position, of the last North Amer-
ican icecap. Kelly and Dachille point out that the area occupied
by the ice was similar both in shape and in size to the
present Arctic Circle (248:39). Many geologists have remarked
on the unnatural location of the icecap. It occupied
the northeastern rather than the northern half of the con-
tinent. Some of the northern islands in the Arctic Ocean,
and northern Greenland, were left unglaciated (87:28, note).
Alaska and the Yukon had mountain glaciers but no con-
tinuous ice sheet. Then, the ice is known to have been thicker
