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

EARLIER DISPLACEMENTS OF CRUST 275
The method used was that of trial and error. I selected a
possible location, and then searched the available evidence
to see whether that location was reasonable. I tried many
locations, giving up one after another as facts turned out to
conflict with each of them.
After the Hudson Bay location had been settled to my
satisfaction, I considered, for a while, that the previous position
might have been in Scandinavia. I was forced to abandon
that idea. Other positions, investigated in turn, included
Spitzbergen, Iceland, and Alberta. There was a great deal of
shifting back and forth.
Finally, clarity began to set in; ever more numerous facts
began to fall into place, and at last I had reason to feel that
my feet were on solid ground. The previous position of the
pole was, I concluded, in or near southern Greenland, or
between Greenland and Iceland. That is, the Greenland
region then lay at the pole.
I repeated the process, with this polar position as the cen-
ter of my circle, and a rather flexible radius, and came up,
to my considerable surprise, with a pole somewhere in or
near Alaska, perhaps in the Alaska Peninsula or in the Aleu-
tian Islands. This third pole takes us back to about 130,000
years ago, and of course the evidence for it is much slighter
than that for the Greenland pole. Despite the fact that this
hypothetical position is hardly more than a suggestion to
guide further research, it is highly important because it
serves as a point of reference to "box in" the Greenland pole.
It is impossible, with the evidence now at hand, to recon-
struct any earlier displacements of the crust. However, evi-
dence of a late Pleistocene continental glaciation in Eurasia
suggests the possibility of one or two former polar zones in
that land mass. Though this evidence has been known to
Russian geologists for many years, it has attracted the atten-
tion of Western geologists only since 1946 (219). One of these
positions may account for the so-called "Riss" glaciation in
Europe.
