EARTH'S SHIFTING CRUST
5,000 or minus 3,200 years (an unusually large margin of
error) indicates glacial conditions at that time, and a rough
extrapolation based on the rate of sedimentation indicated
for the dated part of the core would indicate that glacial con-
ditions began in New Mexico not more than about 40,000
years ago. A most remarkable thing about this core is that it
indicates temperate conditions from this point all the way
down to the bottom. When it is considered that the older sec-
tion dated by radiocarbon, about 27,000 years old, was only
28 feet down in the core, it is evident that the core covers a
very long time.
This climatic record has some very important implications
for us. It appears to show, for one thing, that the glacial
period in North America generally did not extend back as far
as the glacial period appears to have done in the North At-
lantic and in Europe. It seems to show, unmistakably, that
the so-called Sangamon Interglacial
continued without a
break, down to about 40,000 years ago, at least in western
North America. Thus, it implies that the Sangamon Inter-
glacial in North America was contemporary with the earlier
part of the Wiirm glaciation in Europe. This is a remarkable
state of affairs, and appears to dispose irrevocably of the doc-
trine of the simultaneousness of glaciations. Incidentally, it
provides confirmation of climatic conditions in New York
State suitable for the mastodons and other animals that lived
there before the growth of the Wisconsin icecap. It is there-
fore in agreement with our assumption of a pole in southern
Greenland. This core, the data considered above from North
America and the Arctic, and the Antarctic cores give us a tri-
angulation that provides extraordinarily strong confirmation
of the theory.
There is one factor, however, that may enter into the inter-
pretation of this San Augustin core, which could invalidate our
conclusions. The plains are now at an elevation of 7,000 feet
above sea level. The earlier chapters of this book have ex-
plained how displacements of the earth's crust may cause
major changes in land elevations. A change in land elevation
