EARTH'S SHIFTING CRUST
Another interesting argument is used by Antevs to buttress
his position against radiocarbon dating. It is based on the
evidence of crustal warping at the end of the ice age. Radio-
carbon dating would, he says, require a fantastic rate of
crustal warping, considered impossible by geophysicists. He
says:
My dating of the Cochrane stage at 11300-10150 B.P. is directly
supported by the fact that long ages were required for the crustal
rise which has occurred in the region since its release from the ice,
At the south end of James Bay the rise of land relative to sea-level
amounts to 600700 feet. . . . The upward movement of some 650
feet equals the rise of the Scandinavian center of uplift during the
last 8,200 years. Since the rates of modern uplifts are similar, 01
one meter a century in the Scandinavian center, and probably 70-80
centimeters (2.3-2.6 feet) a century at James Bay, the past rates ma}
also have been similar. Since, furthermore, the uplifts in the two
regions may have been essentially equal in general, the regression of
the shore line in the James Bay region by some 650 vertical feet
must have taken several thousand years, perhaps 8,000-10,000
years. . . . (108:520).
However, a displacement of the crust, with America moved
farther than Europe, would solve this problem. Processes of
adjustment of the crust would have a velocity proportional
to the amount of the displacement of the particular area. B)
assumption, North America was displaced more than 2,ooc
miles to the south, but the southward displacement of the
glaciated area in Europe amounted to only about 500 miles,
The assumption of crust displacement offers the first possi-
bility of reconciling the observed rates of crustal warping in
America with geophysical principles.
5. Changes in Sea Level at the End of the Ice Age
There was a remarkable number of changes in the elevation
of lands, and their interconnections, at the end of the ice age
The idea that they can all be explained either by a general
rise of sea level due to the melting of ice or by the isostatic
