EARTH'S SHIFTING CRUST
A second vital question raised by the core is the existence
of a warm North Atlantic 70,000 years ago: the foraminiferal
studies made in connection with this core show that the
North Atlantic was warmer then than now. There has been
no explanation of this, yet obviously it is enormously im-
portant. It may be explained by a polar position in the
Alaskan region. We will return to this question in connec-
tion with the other evidences for the location at that time
of Alaska at the pole.
Deposits of volcanic glass shards are not, from our point of
view, something to be passed over without remark, especially
when, as in this case, the deposits relate themselves remark-
ably well to critical phases of our assumed crust displacements.
The last such deposit agrees in time with the Gary
Advance of the Wisconsin ice sheet, and may be considered
as possible evidence of the intense volcanism that may have
accompanied and, indeed, caused that glacial advance. The
older band of volcanic shards also apparently coincides with
a time of great change, as indicated by the Arctic cores al-
ready discussed. That was the time when, according to our
theory, the displacement started that was to shift Greenland
from, and Hudson Bay to, the pole.
It appears to me that the dating of the brief intervals of
glacial deposition also has significance. For example, a brief
interval of glacial deposition between 50,000 and 51,200
years ago immediately follows the deposition of volcanic glass
shards, which according to our theory can have represented a
period of massive volcanism, which may have acted as the
direct cause of the glacial advance, which, in turn, may have
led to the deposition of the glacial sediment in the sea. Of
course the finding of volcanic debris and glacial sediment in
sequence in the same core is an accident in one sense, for a
else on
prolonged episode of massive volcanism anywhere
the surface of the earth would have produced the advance of
glaciers adjacent to the Atlantic. During any movement of
the crust, we may assume that volcanism would be very active
in many parts of the earth, and not necessarily in the immedi-
