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

PAST THEORIES OF POLAR SHIFT gj
the earth and its properties, and the conclusion is reached that,
whereas polar wandering was formerly considered impossible, it now
seems to some, at least, inevitable. These re-examinations were in-
spired by deductions based on the rock magnetism studies of the past
few years (428:86).
In 1954 the results of one of these studies were made public
by the British scientists Clegg, Almond, and Stubbs. They
found impressive evidence of changed directions of the earth's
magnetic field in past periods
and concluded:
Finally, it seems therefore that the most likely explanation
of the
observed horizontal direction of magnetization of the sediments
studied is that the whole land mass which now constitutes England
has rotated clockwise through 34 relative to the earth's geographical
axis. . . .
If such a rotation of England occurred, it could have been a local
movement of a part only of the earth's crust, or alternately, the earth's
mantle could have moved as a rigid whole relative to the geographical
poles. The first hypothesis would consider the rotation either as a
purely local movement or as part of a drift of large continental land
masses. The second would adduce pole wandering as the operative
mechanism. . . . (81:596).
Many speculations regarding polar changes are being put
forward at the present time without suggesting any mecha-
nism. Thus, in recent months Soviet scientists writing for the
newspaper Red Star had the North Pole situated at 55 N.
Lat. 60,000,000 years ago, and in the Pacific to the southwest
of Southern California 300,000,000 years ago, while in this
country Munk and Revelle suggested that the South Pole
was once over Africa (315).
Needless to say, none of these concepts has been brought
forward without evidence. The evidence is converging from
many directions, with an effect of the confluence of many
rivers into one mighty torrent. The summary of the evidence
is the business of the following chapters.
