EARTH'S SHIFTING CRUST
Now, what Dr. Antevs says is that the radiocarbon dates
from America don't make sense, and the radiocarbon method
must be wrong (9:516). He attacks the method because the
rates of withdrawal of the ice which it suggests are to him
fantastic. He complains particularly about the disproportion
in the indicated speeds of withdrawal in America and Europe.
The radiocarbon method has indicated that the Mankato
Maximum occurred between 11,000 and 10,000 years
ago. This stage has been related chronologically to the socalled
Salpausselka Stage in Europe. Antevs considers this
totally unreasonable, because
This correlation equates a point at less than one-quarter of the
American ice-sheet radius with one at the half way mark in Europe.
Clearly this lop-sided matching cannot be right.
He says, further:
Other implications are equally unreasonable. . . . The Canadian
ice sheet would still have touched Lake Superior when the Scandina-
vian ice sheet had entirely disappeared. . . .
Antevs makes the conflict more explicit, as follows:
The North American ice sheet would still have extended to the
middle of the Great Lakes when the Scandinavian ice sheet had en-
tirely disappeared, for the latter had melted from the Angermanalven
basis by 8550 B.P. [Before the Present], and from Lapland by 7800
B.P., and what is more, the ice would still have lingered in these lakes
while the distinctly warmer Altithermal [Climatic Optimum] came
and went. The ice retreat would have been exceedingly slow during
the Altithermal but extraordinarily rapid during the last 3500 years,
which have been only moderately warm (9:519).
Antevs is therefore driven into a blank rejection of radio-
carbon dating. He insists, in contradiction to all such datings,
that the icecap must have left the Canadian Mattawa Valley
about 13,700 years ago, and that the Mankato Maximum
(which he refers to as the Valders Maximum) must have oc-
curred about 19,000 years ago (9:520). In the discussion in
the pages of the Journal of Geology, between him and Mrs.
de Geer, Mrs. de Geer insists on the high reliability of the
