much more continuous than has been supposed, but confined
to smaller parts of the earth's surface at any one time. Further
support for this view is provided by the geologist Stokes, who
remarks, in connection with the history of the Rocky Moun-
tains:
Although the Rocky Mountain or Laramide Revolution is popularly
supposed to have occurred at the transition from the Cretaceous
to the Tertiary, it has become increasingly evident that mountain
building was continuous from place to place from the late Jurassic or
early Cretaceous and that deformation continued through the early
Tertiary and Quaternary (405:819).
In other words, mountain building went on continuously in
North America from the Jurassic Period, about 100,000,000
years ago, into the Pleistocene Epoch,
have come to an end 10,000 years ago!
which is considered to
This is excellent evi-
dence in support of the conclusion that, in all probability,
none of the alleged mountain-building revolutions occurred
in widely separated periods, with long, quiet periods in be-
tween.
Krumbein and Sloss point out that this view is, in fact, be-
coming widely accepted by geologists. They
remark that
"Gilluly . . . recently examined the evidence for and against
periodic diastrophic disturbances, and he showed that such
disturbances are much more nearly continuous through time
than is generally supposed," and they conclude:
Added complexity arises as additional stratigraphic studies afford
data which imply that tectonic activity is continuous through time.
The classical concept that a geological period represents a long in-
terval of quiescence closed by diastrophic disturbances is not fully
supported by these newer data (258:343).
