| While the field of vertebrate
paleontology is somewhat aside
from my line of endeavor, We, as
biologists, depend upon it for in
formation regarding the region and
ancestry of modern land animals.
We, are all aware, through the dis
eoveries of Dr.. Siegfriedt, of the
important role which the Big
horn basin has played in adding to
our knowledge of animals of the
| past.
Zone may easily realize, then,
why paleontologist is enthusiast
tie about the region in which we
!. are working, be his interests along
either invertebrates, vertebrate, or
plant lines.
From the Pryor mountains on
the east to the Beartooth front the
geologic section is as complete as
anywhere in the west, from the
oldest period when plants and yer
tebrates had not yet evolved, and
invertebrates were of the simplest
types, to tn elatest period when
plants and animals We're of the
modern aspect. In the Beartooth
front, along the white Palisades,
we find a repetition of the same
ancient marine limestones as is
found in the Pryors, mute evidence
Of the mighty dynamic forces of
the earth which bent and broke the
layers of rock along the line of
the present front. In the same
limestones as along the Palisades,
horizontal remnants of the once
continuous layer which extended
over the granite masses of the
Beartooths and connected with the
Palisades. Further west of Bear
tooth Butte the ancient landscape
is covered with htiek sheets of vol
canic lavas, which are coextensiva
with those of Yellowstone national
park. Realizing fully the signif-
ieance of the fossil material in
the geological research work which
we hope will be continued in this
region, collections have been made
from as many horizons as have
been discovered. From the Bear
tooth Butte region alone collections
have been made from horizons III
rocks of three distinct geologic
periods. Much of this material
will be carefully studied in our lab
eratories at Princeton university.
! Duplicate material of identified
specimens will be returned to Red
Lodge, in the hope that they may
assist others who are interested
in the problems of the region.
I'm addition to the mere collect
ing of fossils the summers work
has included the measuring and
detailed study of several complete
geological sections. Messrs. Keith
and Hulett have measured the
Lance-Fort Union section from
| Dry Greek to Bearcreek, while
| Messrs. Foote, Bell and I have at
tempted the same thing on Bear
tooth Butte. 1t is hoped that III
! the summers to come it will be
i possible to complete many more
| such sections throughout the reg
ion and to locate many more hor-
lions as lucrative in fossil remains
as these few which have been ex-
plotted during our first summers
work."
Structural Geology Explained By
DR.. E. L. Perry
DR.. E. L. Perry, Of Williams col
lege, spoke in detail on structural
geology of this region in which he
explained the following:
Cone of the principle lines or
research in this region is embodied
the term structural geology, the
arrangement of rock masses. Dur
ing the past season a study was
made of the mountain front in the
immediate vicinity of Red Lodge
with the intention Of mapping and
studying the position Of the var
ious strata and determining as far
as possible the mechanics of noun
tain building.
ut is now possible to say with
certainty that the dominating
, structure along the mountain front
, | is an overthrust fault and not :
normal fault as originally suppos-
ed. Most of the minor structures
are related in some way to The
Goust, in. the lower Pyrenees,
was recognized as an Independent
state by France and Spain in the
early Seventeenth century. 1t has
barely one mile of territory and a
, population of about $50. The sole
occupation of it's people is the
