Coffin Studies Fossil Forest Formation
The volcanic explosion of Mount St. Helens has provided
Harold Coffin with a massive laboratory in which to examine various aspects of
fossil forest formation. For about two decades, Coffin has been studying the
fossil forest of Yellowstone to determine what mechanism might be responsible
for its formation. If one counts the tree rings on each of the layers found in
this fossil assemblage, the total time span required for this forest to grow
there would be about 14,000 years. Coffin has developed an alternative
explanation based upon evidence for the transportation and rapid burial of the
trees.
The largest problem that Coffin faced was how trees could
remain upright in a catastrophic situation. At first it was assumed that
transported trees would be almost exclusively horizontal when finally deposited;
yet in some areas of the fossil forest a majority of trees are vertical,
suggesting that they are in growth position.
Log Raft
The blast of Mount St. Helens resulted in the devastation
of many square miles of mature forest. One aspect of the blast was the placement
of a large log raft on Spirit Lake which was only a few miles from the crater.
Logs and stumps have been floating in the lake for over two years. Coffin's
observations at Spirit Lake have confirmed earlier laboratory experiments in
which he placed small trees in water tanks and let them float there. With time,
most of them moved from a horizontal to a vertical position. The experiments
have been criticized because the trees were not as large as those found in
Yellowstone. Coffin's observations this summer have now answered this criticism.
In Spirit Lake at the present time, many very large trees are
floating in the vertical position, much as the small-scale experiments had
indicated they might. To establish that these trees were not attached to the
lake bottom, divers examined a number of these upright trees and found them to
be free floating. In addition, it would not be possible for the St. Helens trees
to be in place of growth because the bottom of the lake was filled with about
200 feet of sediment.
Coffin's data and interpretations of the events in Spirit
Lake have been published in the May 1983 issue of Geology.
These data suggest that erect petrified trees need not be in
a position of growth but that water-transported stumps also may be deposited and
preserved upright.

North Dakota Forest
In addition to the St. Helens work, Coffin also examined,
this past summer, another fossil forest in North Dakota. Though this forest
certainly is not as well known as the Yellowstone forest, Coffin was able to
examine what appeared to be several layers containing upright trees.
Unfortunately, the state of preservation of these trees will not allow
dendrochronological studies as have been done in Yellowstone. However, the
extensive placement of these trees has prompted Coffin to say that they are
worthy of further study and are in his plans for a future summer.
GRI's Summer Research Plans
With the beginning of the summer season, some of the GRI
staff will be in the field to continue their research efforts. R. Tkachuck will
be spending a month at the Walla Walla Marine Station at Anacortes, Washington.
There he will be examining the biochemistry of a species of tapeworm which lives
in the spiral valve of a chiamarid fish (known locally as the rat fish). This
tapeworm differs from the majority of other tapeworms in that it has only one
segment rather than many. It is considered by evolutionary biologists to
represent an early step in the evolution of tapeworms. By examining its
biochemistry, Tkachuck hopes to determine whether this worm deserves this
taxonomic position.
Biochemical analysis of the metabolic products of glucose and
certain amino acids will be the first experiments performed. Since parasitic
organisms tend to show significant loss of metabolic abilities when compared
with free living forms, these experiments may indicate how "primitive"
this creature is.
Log Mat
H. Coffin will return to Spirit Lake near Mount St.
Helens to further monitor the state of the floating log mat upon the lake. He
will make further surveys of the number of upright trees versus the number of
horizontal ones. A period of time will also be spent in the Yellowstone area
working on the dendrochronological picture of trees found in different
horizontal layers. At this time he will be collaborating with Dr. Art Chadwick
and his graduate student Mike Arct. Finally, some time will be spent doing
preliminary studies of the fossil forest in North Dakota. Here he will attempt
to determine the mode of formation of the various layers, the kinds and number
of varieties of the trees in this forest as well as some paleoecological studies
to determine the kind of environment this forest once occupied.
Organic Profiles
R. H. Brown will continue with computer analysis of C-14
levels in layered organic profiles. This analysis, now localized at Loma Linda,
is a continuation of studies originally begun in the Andrews University
computing facility.
Sedimentary Layers
A. A. Roth will be examining various sedimentary layers
in Utah and Colorado with the hopes of determining more fully the conditions at
the time of deposition. By examining the size of the materials composing a
particular layer, it is possible to postulate the forces involved in its
deposition.
Field Conference
In addition to the above research activity, members of
the GRI will participate in a field conference held for certain administrators
of the Mid-America area, various educational conferences and BRISCO. Finally, a
field conference for the General Conference and Division leaders of the
Seventh-day Adventist Church will be held in mid-September. By the first of
October, the fall activities at LLU should begin.
Brown Presents Paper on Radiocarbon Modeling
R. H. Brown, past director of GRI, presented a paper at
the 11th International Radiocarbon Conference in Seattle, Washington. Though
officially retired, Brown is actively pursuing his research in radiocarbon
modeling. Dr. Ivan Rouse of the Loma Linda University Physics Department
collaborated with Dr. Brown in preparing this paper entitled "Long-Term
Response of the C-14 Exchange System." It modeled long-term aspects of the
flow of radiocarbon from its formation in the upper atmosphere into various
components of the biosphere, and finally into the deep sediments of the ocean.
The results indicate that the probabilities for radioactive decay to Nitrogen-14
and for transfer from the deep ocean into the upper biosphere are each greater
than the probability for transfer to sediment, and also that the C-14 exchange
system may at present be at only approximately 91% of equilibrium with respect
to the mean current rate at which C-14 is introduced into the biosphere.
A 9% deficiency from equilibrium is less than the range of
fluctuation that can be expected from variations in either the cosmic ray
intensity or the geomagnetic field intensity. If the C-14 inventory has been
increasing steadily and has reached only 91% of equilibrium, uncorrected C-14
ages in the vicinity of 4000 years BP would be only about 750 years greater than
the corresponding historical age.
According to the conclusions reached by Brown and Rouse,
harmonization of C-14 age dates with the constraints of biblical chronology
requires an extended post-flood injection of C-14 into the biosphere at a
greater rate than the present value of 8.2±1.5 kilograms per year.
GRI Conducts Field Conference
An 8-day field conference was held for the leadership of
the Pacific Union Conference during the summer of 1982. This study tour was
requested by Walter Blehm, president of the Pacific Union, in order to acquaint
his personnel with the problems and solutions encountered in the study of
origins. Starting in Holbrook, Arizona, the group traveled as far north as Moab,
Utah, and eventually returned to the Zion area of Utah.
A variety of geologic features provided the springboard for
discussions on the various interpretations possible for the stratigraphic
record. Unconformities which occurred at places where portions of the geologic
column are missing were displayed in numerous locations. These gaps range from
12 to over 170 million years, yet the bedding plains were even and straight over
thousands of square miles. This even erosion is of a type not occurring on earth
today and one which defies a suitable mechanism.
Study in the Grand Canyon and Zion/Bryce Canyons allowed the
participants to follow the geologic column from its Precambrian base to nearly
the top of the Tertiary. Few places on earth provide such a continuous display
of the various geologic layers.
At the Grand Canyon, A. A. Roth discussed several models for
its formation with the final conclusion that data at present do not strongly
support any particular model. Roth noted that the current trend in geological
thinking is that the canyon formed relatively rapidly (in geological terms, to
be sure).
Evidence for catastrophic placement and erosion of sediments
were seen in the distinctive turbidite sequences found in numerous localities. A
sequence of rapid erosion was seen in the Kanab Creek which eroded 40-50 feet of
soft sediments in one overnight rainstorm.
The use of CB radios allowed for lively conversation between
drivers and passengers of the 10-car caravan. The attending leadership expressed
the need for their constituency to become acquainted with both the problems and
explanations produced by a study of origins.
Field trip participants in Petrified Forest National Monument, Arizona, examined coarse conglomerates (note directly behind people) and bentonite, an important factor in rapid erosion.
Roth's Research Published
The results of an extended research project on the
relation of light to coral reef growth was recently published by Ariel A. Roth,
Director of GRI. Conducted in Hawaii and the Marshall Islands, this research
analyzes: 1) the effects of ultraviolet light on rates of coral growth, 2) the
relation of light intensity to rates of growth, 3) the effect of natural
day-and-night cycles to rate of growth, and 4) the lag effect of light
irradiation on the coral growth rates. The results, published in Pacific
Science (Vol. 36, pp.65-81), indicate that ultraviolet light inhibits coral
growth at the surface of the ocean where rates of coral reef growth are usually
studied. This no doubt is responsible for some of the slower rates of coral reef
growth that have been published earlier. Coral reefs do not grow as rapidly on a
dark cloudy day as they would on a bright day, they grow more slowly at night,
and there is a light-lag effect.
The rate of coral reef growth is important in
creation/evolution studies, because the very long periods of time assumed
necessary for some reef growth do not fit within the standard biblical time
frame. However, there are some records of rapid growth that permit one to
accommodate reef growth within a short chronology. Ultraviolet light inhibition
described in this research may be part of the reason for the discrepancy.
New Edition of Creation Book
Rapid increase in knowledge causes science books to become
outdated quickly. Creation: Accident or Design by Harold G. Coffin was
published in 1968. In the fifteen years since it was written much new
information of interest to science and religion has appeared. Furthermore, this
volume has been out of print for two years.
An expanded and much revised second edition was submitted to
the publisher over two years ago. Currently it is in the hands of the copy
editors, and the projected publishing date is for fall 1983. It will appear
under the new title, Origin by Design.
Clyde Webster Joins the GRI
Clyde L. Webster, currently chairman of the Chemistry
Department at Walla Walla College, will become a full-time member of the GRI in
July, 1983. Webster finished his undergraduate work at Walla Walla in 1968 and
completed his Ph.D. in 1972 at Colorado State University in Fort Collins. His
dissertation subject was selenium isotopic analysis in uranium role-front
deposits.
Upon completion of his graduate work, Webster was
self-employed as a consultant in analytical service which performed trace
elemental analysis on a variety of geologic and industrial samples.
Trace Work
A recipient of several GRI research grants in the past,
Webster is presently working on the trace elemental analysis of dated lava flows
from Hawaiian volcanoes.
In this work he is testing the idea that each separate flow
should have a characteristic elemental fingerprint. After these studies he will
examine the volcanic material in the various layers that surround the trees in
the Yellowstone fossil forest. It may then be possible to determine how many
volcanic episodes were necessary to form the deposit.
Webster is married to the former Priscilla Wilson and has two
daughters, Kristine, age 14, and Laurel, age 11. In anticipation of joining GRI,
Webster commented that the creation/evolution controversy is a critical area of
study in these times and that he hopes to use his geochemical training to
understand more fully the past geologic record.
The GRI is pleased to welcome the addition of this very
competent scientist to its staff.
BRISCO Meets in Glacier National Park
Glacier National Park on the Montana-Alberta border served as the site for the annual convening of BRISCO (Biblical Research Institute Science Council). Meeting sites are chosen so that attendees can view a geologic or paleontological feature of significance for the evolution/creation controversy. This past year, the group examined the contact between the Precambrian and the Cretaceous layers of the Lewis Overthrust, an area which suggests that several massive strata have overridden other layers of the same sequence. The action has resulted in the geologic layers being "out of sequence," with Precambrian rock on top of layers found much higher in the stratigraphic record.
Overthrust Layering
Several creationists in the past as well as the present
have interpreted the out-of-sequence layering found in overthrust areas to imply
that the geologic column is not meaningful. An underlying reason for denying the
orderly sequence of the geologic column is that it would make much more
difficult the evolutionary claim that the geologic column is a sequential
history of life on earth.
A number of major overthrusts are described throughout the
world. If these features are really not overthrusts but do indicate that the
geologic column is random, then the present understanding of the geologic column
would require drastic reinterpretation.
Marias Pass
The group undertook the challenging climb in the Marias
Pass area which required about 3 hours to reach the contact between the
Precambrian and Cretaceous layers. At the contact site the lower Cretaceous
layers and the upper Precambrian layers were examined. Clear evidence of sliding
of one layer over another was seen in the way the rocks were deformed and by the
formation of striations, polish, slickensides, etc. The consensus of the group
was that the evidence did indeed suggest an overthrust area.
Other work at BRISCO involved the presentation of prepared
papers on subjects dealing with biblical interpretation, the process of
discerning truth, and a special section dealing with methods of communicating
Christianity and eventually creation with the secular scientist.
Roth Teaches Field Course
A LLU 4-week summer field course in historical and
philosophical interpretations of paleontological and geologic features was
conducted this past September by A. A. Roth, GRI Director. In comments to the
students, Roth stated that it was his intention to expose them to some of the
most difficult geologic problems that face the evolutionist and the creationist.
The tour covered close to 5500 miles in the western United
States and included visits to the fossil Permian "Reef" in southern
Texas, the multi-layered evaporite deposits of the Castile Formation, the
volcanic and coal complexes of NE New Mexico, the tremendous Heart Mountain
thrust sheet, the fossil forests of Yellowstone, Wyoming and Florissant,
Colorado, the erosional features of the Grand Canyon and many other fascinating
geologic sites. Along the way much evidence supporting a catastrophic history
for the earth was also seen.
The 29 participants of the 10-car caravan were able to
examine numerous rock out-crops and fossil areas which aided their search for
interpretations of the past history of the earth. A wide variety of backgrounds
was represented among the attendees mostly graduate students from several
Adventist colleges. Also, three graduate students from universities in Holland
attended the class. Commented one attendee, "This trip is probably the
fastest way that one can learn both the difficulties and benefits of the
creationist point of view." Roth believes that an intensive study of the
facts and various interpretations is necessary in this important area and that
the total scientific data alone favors the creation concept of origins.
The course is usually offered every other year and is open to
any interested college or graduate student who has an adequate background.
Interested students should contact A. A. Roth at GRI for future classes.
GRI Announces Research Grant Awards
Research grants totaling $22,050 were awarded to 7 individuals for 1983. Each year GRI accepts applications for proposed funding of research which centers on the problems in creationism. The grants are open to individuals in academic institutions, and the spectrum of possible research areas is quite broad. The award grants represent newly initiated work as well as funding for continuing studies. This year half of the awardees were graduate students working towards advanced degrees. The list of recipients continues below:
