Introduction
This is about the meteors, asteroids
and comets that bombarded the Earth over the last billion years or
so, how those impacts created our geography, and how man has
used those land forms. What drove me on this research is the
increasing exactness in which these discoveries were made. As a
child, my family would take excursions in the car, to see the
country and what was there. To keep me occupied, my Mother would
give me the map, and she showed me how the different lines and
symbols meant different things. From that, I learned to read and
understand the maps, and this set me on a course of my life that I
would read and collect all the maps that I could find of the area
where I was, because they gave me a better understanding of the
world around me..
In my mid 20's I was living in the State of
Oregon and I came across a map of Oregon that was hand drawn, but
done so to a very high degree. As I studied it, I found what looked
like a large crater in the southeastern part of the State. Comparing
that to other maps I had, I could only get rough 'Maybes' from them
for confirmations of the idea. Then one day I ran into a much older
man, a professional geologist (whose name is long ago gone), who I
thought would have some insight into this, and I queried him on the
idea. His response was that there were no craters on the Earth, and
the reason it looked like one to me was because the map was hand
drawn.
That didn't answer my curiosity in
the way I wanted to hear, but at the time there were no other
sources of information available. And it stayed that way until
Google Earth came along. Using that I found my childhood home, where
I kissed my high school sweetheart, and a number of other such
things, and then I remembered that map! "Is that possible?", I said
to myself. So I went to Oregon on Google Earth and looked, and there
it was, plain as day. And then - there was another one.... and
another and soon I had circles that described nearly every
geographic feature of those high desert plains.
That started a journey of discovery. From
there I started to see how the land was formed, over and over again
there were circles, just like on the Moon. Yes, they were eroded,
covered with vegetation or farmed over for many years, even centuries,
but the main features were there. These impact circles formed the
mountains, the rivers, the coastlines and more, all over the
world. Then after a time, I started to see that many of these
impacts left not just one circle, but a series of concentric circles
around them, seismic shock wave circles. And, I was increasingly amazed
at how these circles expanded over vast distances, forming the
geography of places hundreds and sometimes thousands of miles away from
the impact. Then I started to see how man has been using the land forms
created by these seismic waves, and so the research continues.
While much of this work is here
simply to demonstrate why our world is as it is, it is also here to
provide overwhelming evidence of the impacts, and how the Earth was
formed to the non believers and the professionals who refuse to look
at anything unless it was in their 19th century based text books.
Hopefully some of you will use these
studies as a template, and begin a search for discoveries of your
own as there is still much to be done. And when you see those
geographical features falling exactly on that perfect circle, you
will say as I did "No Way!", "Are you serious?", "That's
incredible!" Then by studying more of the evidence you will see that
yes, it is serious. Yes, it is incredible. Our world did came to be
by Catastrophic Impact, and the remains of those impacts, those
Seismic Circles, are what we know today as Geography.

These people have put together the best of the
imagery of our Earth so that we can see and study our world in a way
that was not possible before. They have created the tools which
allow us a new understanding.
It is a
commonly accepted theory that all the continents of the Earth were
joined at one time into a super continent named Pangaea. Then for
some reason this super continent broke up into many pieces, or
sub-continents. These sub-continents then floated around on the
surface of the Earth, sometimes colliding with one another, one
rising to form the mountain chains, and the other diving down
returning the surface to magma. At these boundaries, volcanoes
form which spew lava and ash which re-covers the Earth, all of
this like a giant boiling pot. Then erosion from the atmosphere
carves the river valleys and glaciation wipes everything clean.
Now, finding any traces of anything that happened before all of
this is further complicated by the plant life that covers the
planet reclaiming any remains.
This
idea of Pangaea comes from the early 1900's where from a map of
the Earth, it appeared as if the east coast of South America, and
the west coast of Africa would fit together, if you cut the
continents out of the map and then thought of them as a jig-saw
puzzle. Then with enough imagination, subduction, erosion,
volcanoes and the all powerful 'fudge factor', you could fit all
the pieces back together into the super-continent Pangaea, in one
shape or another. From there, if it happened once, it probably
happened several times before. And so the modern Geo-sciences were
born.
However the
question comes up "If the oceans were 100 feet higher, 100 feet
lower, or did not exist at all, would we ever have had a theory of
Pangaea?"
Secondly, in regards to the surrounding planets that we have been
able to photograph and examine with some clarity, the Moon, Mars, Venus
and Mercury, why do we not see evidence of floating continental plates
there, but instead see landscapes pockmarked by a billion years of
meteor impacts?

The Far Side of the Moon
Until recently all of our observations
of the Earth were made on the ground. Geographers measure the surface
of the Earth and plot their findings on paper drawing maps of all
sorts. While these maps are necessary and useful, using them as a
basis for the Earth sciences is problematic. Maps are drawings of what
we understand to be there, rather than the real thing, and the
various projections used to draw the surface of a nearly spherical
Earth on a flat sheet of paper distorts the dimensions, or cuts the
geography into pieces, leading sometimes to questionable conclusions. Then
came aerial surveys, photography from five or six miles up. These
are good for property analysis, roads and land use planning. From these are drawn maps of excellent quality, but
even with these we cannot see enough of our planet to get a good
look at it, as many of the features of our Earth are 10s or 100s
or 1,000s of miles across.
Geologists use microscopes, gas chromatography, radiation, spectral
analysis or other means to analyze what they found on or near the
surface. Sometimes they find shatter cones, microscopic diamonds or
iridium layers and this is evidence that a meteor impacted the Earth
there. This evidence is then compared with other findings to
confirm the impact. This seems to work for smaller impacts, but the
larger ones are beyond the scale of these methods. Then to try to
understand the past, theories come up about dust clouds from the impact
that blocked out the sun, super tsunamis and strange gases that killed
off all the dinosaurs with this impact or that one, many millions of
years ago.
To
understand our Earth, we need to see it as the sphere that it is,
and we need to be able to see it at distances where the geographic
features can be seen in their entirety, and in relation to the
surrounding area. And, we need views that are as free of clouds as
possible. Satellite imagery is the only way to do this.
Google
Earth has made this possible. They have assembled the imagery of a
myriad of organizations and companies, which have been filled with
an untold number of highly skilled scientific people, all with the
quest to understand our Earth better. They have provided us with a
tool from which we can see our entire planet from its' entirety,
down to fine geographic detail. With this comes new understandings
of our Earth.
Our
Earth was built over billions of years by the bombardment of an
untold number of asteroids, meteors, comets, and extra terrestrial
objects of all kinds, shapes and sizes, just like the Moon, Mars,
Venus and Mercury. These impacts created the form of our Earth,
building it up layer by layer, one impact after another. Gravity
then pulls the Earth into a nearly perfect sphere, and the
rotation of the Earth causes a bit of a bulge around the Equator.
Then, with erosion from the atmosphere, vegetation covering things over, glaciation, volcanoes and
other natural forces, we have what we have today.
While very small impacts may have
been obliterated by time and erosion, the larger impacts left
substantial marks and many times in grandiose design. In fact,
these impacts gave us our geography. They are the valley that the
river flows in, the mountain top Skyline Drive that gives us those
exhilarating views. They are the coast lines, the national parks
and the dirt you walk over every day. The formations left from these
impacts are where towns and cities where built, and many of them
are our political boundaries. Often they define the way we plant
our crops, where we build our roads and reservoirs, and where we
find the minerals that enrich our lives. These impacts placed the
volcanoes and the fault lines where earthquakes occur, and they
shaped the continents.
This new evidence demonstrates that the
surface of the Earth has remained relatively unchanged for a long, long
time. Where it was thought that most of the formations of Earth were
formed slowly over millions of years of time, in fact most of the
formations on the Earth came to be by catastrophic impact. These
impacts then caused seismic shock waves which expanded across the Earth
in the form of concentric circles similar to a stone thrown into a
still pond of water. While our atmosphere and time have eroded these forms, the remains of these seismic waves are precise and
still clearly visible today. Where it was thought that the mountains
were raised by continents colliding, and the rivers formed by erosion,
it can be shown now that the mountains were raised and the rivers valleys were formed by
these seismic circles.
While it is
certain that the crust of the Earth is shifting in places,
which is the cause of earthquakes, this is something quite different
than the idea of Pangaea and continental plates floating on the surface
of
the Earth which collide to form mountains. These geographic circles
provide evidence that contradicts those ideas. Many of these seismic
circles are hundreds and sometimes thousands of miles in radius. Some
of them span continents, a few circle the globe and sometimes the
concentric circles from individual impacts are visible on six
continents, Antarctica being too ice covered for analysis. Had the
continents been drifting, then parts of the circles would be moved. Yet
the circles are intact.
Most of the impacts that are discussed
here are huge, but the principles that are shown apply to impacts
of all sizes. By understanding them, the reason why the local
river flows where it does will become evident. Why towns and
cities were built where they were, and where minerals are found
will become more clear. The soil sciences, land use planning,
geology and Earth Sciences generally will have new insights to
advance their knowledge base.
This treatise
is not intended to be all inclusive of all impacts. That would not
be possible. It is intended to demonstrate the major impacts of a
variety of types and how they formed the Earth. Nor is this
intended to be the last say in the formation of the Earth. To the
contrary, it is intended to act as a guide to further research, to
help us form a new understanding of our home planet, how it came
to be, and why it is as it is. What you see here is just a
beginning. The more we look, the more we see. With these new
tools, a whole new world awaits.
|
|
The Beginning
The
idea of an impact is typically a crater like we see on the
Moon. This image of Tycho Crater on the Moon is generally of
how we think of them, as a depressed area with a circle of
steep walls surrounding it, and a central peak. This is only
the case sometimes.
Whether or not an impact raised a
rim when it was formed is dependent on a number of factors,
such as the size of the impactor, the difference in density
between the earth and the impactor, relative speeds, and the
terrain where the impact occurs (mountainous, plains,
water). Also the stronger gravity is, the less steep the
resulting walls can be, and the less high.
A peak in the center is also
a rarity. As the gravity of the Earth is six times that of
the Moon, the impactors come in faster, and hit harder. What
is left is usually smashed to bits and scattered in all
directions, or buried deeply in the Earth.

Far more often than forming a
crater, an impact will end up looking very similar to the
water pictured here. The evidence of impacts lies more in
these circular waves that radiate out from the center, than
in the central area where the hit actually occurred. The
extreme energy of the impact sends out seismic shock waves
through the Earth, powerful enough that the ground acts as
if it were liquid. The difference between the water and the
land, is that the waves in the water will continue until the
water is again a still flat surface. But on the land when
the energy has been expended, the waves stop where they are
and the land retains that form.
These seismic waves travel out from
the center for long distances, rearranging the land as they
go into geographical alignments in the form of concentric
circle waves. We know these alignments as mountains, hills,
valleys, coast lines and other phenomena. Larger impacts
will show concentric circles out to great distances, each
circle with the same center point.
As more impacts occur, the
land then looks more like the water ripples in the rain,
pictured below.

Tamiahua Impact, Veracruz
State, Mexico.
The Impact site is about 95 miles in
diameter.
|
The
shock waves may form a circular rim of hills, or they
form valleys lower than the surrounding areas. Rivers
then form there. This is why many of the rivers flow
where they do, and why many lakes, mountains and
coastlines are where they are, and shaped as they are.
This is the
case for the Tamiahua
impact site on the Gulf Coast of Mexico, pictured
right, where the Rio Panuco defines the northwest edge,
and the Rio Tuxpan defines the southern edge. An
examination of the image at right will show other
smaller impacts, some of them are marked, most of them
are not.
As each impact is marked,
the formation of the land becomes more and more
organized, so that the majority of land forms can be
ascribed to one or more impacts. By defining the land
this way, then the effects of the various other
geological forces can be more easily recognized and
understood.
Since most impacts do not leave
craters, it is more accurate to call these Impact Sites.

Himalayan
Mountains Impact
It is theorized that these mountains may still
be increasing in height due to plate
tectonics. If so, the shape of the plate was
caused by the shock wave of the impact.
|
While
the center of the impact may take many forms, the
seismic shock wave is always a true circle. However
nearly all impacts have one side more pronounced
than the other, due to the angle of impact. The
impactor nearly always comes in at some angle other
than straight down. This means that the shock wave
deformations in front of the impact will be more
pronounced than those behind it. Roughly then, half
of the circle will be easily seen, and the other
half will be more faintly marked. This is how the
varying directions of impact can be noted.
In the image left,
the Himalayan Mountains form a near perfect circle
from the shock wave that formed the mountain
chain. The impactor here then came in from the North
northeast at a steep angle. This is a very old
impact with many impacts after it. These later
impacts obliterated part of the earlier impact to
make shock wave circles of their own. This is one
reason why it is rare that we see a complete circle,
particularly on the larger strikes.
|
Another reason the concentric
circles will not show in their entirety, is that as the
shock wave travels through the Earth, some of the surface is
more easily moved around by the wave than other parts. In
the image below the lower Red River joins the Mississippi
River Delta and aligns perfectly with the shock wave from
the Adirondack
Impact, at 1315 miles distance(2,110 kilometers). Then at the top
left of the image the alignment disappears. This shows the
difference between softer soils, and harder packed earth to
the north. Thus what we see are bits and pieces of the
circle and we must connect the dots.
Yet another reason is that our ability to decipher fine topographic
detail is limited on this scale. A circle of 1,315 miles radius has a
circumference of over 8,000 miles. To track the undulations over all
types of terrain at this distance is a daunting task, as such only the
most obvious can be shown. The image to the right shows about 650 miles
of the arc, from an effective altitude of over 750 miles.
When we look
for the evidence of the impact, the seismic wave
deformations of the land are definitive. These
deformations will be aligned very closely to the
circle, and there will be a number of them spaced
around the circle to define the circle specifically.
The more alignments, the higher the certainty of
formation by impact. More alignments allow the
circle to be drawn with more accuracy, and the
center of impact ascertained more precisely.
River valleys are the easiest to
follow, as the valleys they follow have been
produced by the seismic wave, and their flows are
easy markers following the ring sometimes for
considerable distances. The lines of hills and
mountains that are formed are easily followed, but a
degree less distinct than following the rivers, as
the rivers continually wear down their paths, while
the tops of the hills continually erode. |

The Red River flows to the southeast and
joins the Mississippi River Delta, as formed by
the Adirondack
Impact, in northern New York State at
1,315 (2,110 km) miles distance.
It is not unusual to see the
largest alignments at great distances from the point
of impact, with smaller alignments before and after. This may be a clue as to the speed
of impact. Often, the alignments seem to
reverberate from one side to the other, such that
a major alignment will be seen on one side of the
impact with one ring, and then on a different side
of the impact with the next ring.
|
It is generally not sufficient to
note a shock wave by only one alignment. As the Earth was
impacted many, many times, any one geographical feature
could have been formed by any of number of impacts. The
proof lies in being able to show sufficient alignments to
demonstrate each circle specifically. A larger or smaller
circle will not fit, and moving the circle a little to one
side or the other doesn't work either. There will be a
specific center of impact, which may be far smaller than the
impactor. The impactor could have been an asteroid of 50
miles diameter. But the center of impact will still be a
point, and all shock waves will radiate from that point,
rather than an area 50 miles in diameter. The shock waves
from the impact create a pattern of concentric circles, all
emanating from one specific point, the center of impact.
While the shock wave circles will
be near perfect, the alignments to it may show some
variation. The variations are primarily because rocks rarely
break on the smooth line where you would like them to break.
Instead it breaks along the natural structure lines of the
rock. These variations are rarely more than 1% of the
radius.
The more alignments that
follow the circle, and the more concentric circles found,
the more evidence of the impact. It may be possible to find
one or two circular alignments from any point you want due
to chance. However to find specific circles, and then again
to find concentric circles, brings the probability of chance
closer to zero with each alignment found. Finding the
alignments that follow these guide lines demonstrates the
proof of impact with increasing certainty.
If the impact was in the ocean
the impact may create a huge tidal wave. In the
image to the right, the limit of the tidal wave created by
the Cape
Verde Islands Impact is still visible 771
miles to the east of the impact. The line
closely resembles the high tide line seen on
beaches after the tide recedes. This impact is
the probable cause of the Mid Atlantic Ridge.
The jog in Kinbasket Lake, British Columbia,
Canada and the alignment of the adjacent
mountains were the result of an impact 95
miles (155 km) to the northwest.
|
|
Hill and mountain chains too big for the shock wave
to re-align, break in line with the wave, providing valleys where the
rivers and streams flow. Where it seems that the cracks, or valleys in
the mountains have little order other than that of erosion, the vast
majority can be ascribed to one or more impacts, where the seismic wave
broke the mountains and left the valleys where the rivers flow.

The Columbia River
George is a break in the Cascade Mountain
Range.
It was caused by the shock wave from an impact
220 miles North. That impact caused Mt
Baker, a volcano in northern Washington
State, to form.
|
|
Above is the Columbia River George as it passes
through the Cascade Mountain Range forming the
boundary between Washington and Oregon states.
Before this break, the area to the East of the
mountains and primarily in Washington State was a
large inland lake, fed by the Columbia River as it
drained a large part of the Pacific Northwest and
British Columbia. When this impact occurred, the
shock wave caused this break in the mountain chain,
and the lake drained through here forming the
Columbia River George and many of the geographical
features of eastern Washington state as the water
drained away. |
|
The larger hits
have the potential to crack the outer shell of the
Earth. Some had the power to shape the continental
plates. A knowledge of where these hits were, can
help us define the cracks in the Earth's surface and
the various shifting land masses we have. This would
be a basic area of study for people involved in the
science of earthquakes and plate tectonics.
As some of these circular
alignments are large enough to fall on more than one
continent, they can be used as a form of measurement
for the movement of continents. If the age of the
impact can be determined, then the amount of
continental drift can be established over that time
period. Or that idea can be dis-proven.
With the right tools, these
alignments become easily visible and the formation
of our Earth then begins to take shape and make
sense. |

The impact at Yellowstone
National Park produced a shock wave that
aligns
the San Andres Fault line in California, 760
miles (1,245 km) distance from the center of
impact.

The
actual impact site, the center, may be round or deformed
depending on many variables. What was the shape of the
object? Was it round, or perhaps some other
shape. How did it hit? Straight down or at an angle? Was
it a hard rock asteroid, or a dust ball comet? There are
many variables, but more often than not, the center is
flat, perhaps a little higher or lower than the
surrounding area, but generally flat. On some occasions
the impact may raise a center peak, or make a deep
impression, but most often the center is not much
different than the surrounding area, as the impact
blasts everything flat.
It is common to see a lake
in the center, as the center is sometimes depressed.
On smaller impacts, the farm house and other
buildings may be in the center, probably
because the ground there is somewhat higher, so that
is where they built the buildings. On larger sites,
the center area may have been blasted nearly level
by the impact. These level areas are then excellent
areas for towns and cities to be built, such as
Mexico City, Tokyo or Moscow.
 In
the image at right, the
Ébano Impact, is on the northwestern
border of the State of Veracruz with San Luis
Potosi State, Mexico. This impact is on the
eastern coastal plane of Mexico. The soil there
being relatively soft and wet was easy to
penetrate deeply with a high speed, hard asteroid.
The asteroid itself ended
up deep underground, leaving the surface as a
depression where the lake formed, with a raised
center area, and low hills surrounding it.
|
Often times the object may simply go splat, blowing the
material of its making out across the Earth in all
directions, and leaving little evidence of its existence
other than a few inches of soil.
The image at left is of an area south of
Norfolk,
Nebraska. A first look seems to show nothing but
almost flat farm lands. However if you study the image, the
shapes of numerous impacts will start to form. Click
on the image for more on this.
Often the impact site is best
described by a change in vegetation patterns, this due to
different soil types from one impact to the next. These
patterns can often be seen only from high above. Those
that study the various soil types could benefit from a
knowledge of the limits of each type, as an aid to
agriculture, land use planning and other sciences that base
decisions on soil types and their properties. |
There are many kinds of impacts. When we look at
them we must consider what the object must have
been. On one extreme, it may have been formed
from a solar flare that blew heavy metals out
into space at tremendous speeds. These metals
fused together by solar heat, and then tempered
by the near zero degrees Kelvin of the deepest
expanses of space, could be the hardest material
imaginable. This type of object at incredible
velocities would be like a bullet into the
Earth, penetrating deeply leaving only a minimum
crater, but perhaps sending out a shock wave
that circles the impact site at hundreds of
miles distance.
|
This impact was
one of the hard, high velocity impacts that
punched a hole in the Earth, from which the lava
flowed on a number of occasions. |
They could come from a planetary sized
object that was somehow torn apart to form asteroids such as
in the asteroid belt between Mars and Jupiter. In this case
they could have densities similar to that of the Earth.
Sometimes they may explode when
they hit, where pieces fly off in all directions, like
throwing a piece of dried dirt against a concrete wall. This
is the case of the Tycho Crater on the Moon, shown in the
image at left, bottom center of the Moon.
It is also the form of the impact at El
Perdido, Mexico that blasted rays over half the
country.
The image above
is an impact site in Northeastern
Quebec, Canada. This asteroid came at a
low angle from the SE, and plowed a deep 'V'
while cracking the surface enough to let the
lava flow. The lava flowed both north and south.
As it came up from the center of impact, the
lava cooled to form a cap, which then split in
two as more lava surfaced.
|
Asteroids coming in at
various, and sometimes very low angles, could leave scars
and skid marks on the surface of the Earth. They could plow
a deep long 'V' in the Earth, sometimes plowing deep enough
that the lava would flow.
On the other extreme a comet could have
been roaming the galaxy for billions of years collecting
particles bit by bit and slowly growing to something perhaps
a hundred miles across or more. However, if gravity is
proportional to mass, then even if the comet was 100 miles
in diameter, the gravity of it would be infinitesimal
compared to the gravity of Earth. Considering this, the
comet would then be so loosely packed that only the light of
the sun would be enough to blow material from the surface,
and that would form the tail of the comets we see in the
sky.
Many of the impactors that hit the Earth
were these giant dust balls. This is not to discount their
significance because some of them still contained enough
material to shape the continents and form the mountains.
When they hit a large percentage of the material of their
making is blasted out in all directions to form a new layer
on the Earth. The hit still produces the circular shock
waves which reform our Earth. In the center, the comet
collapses and depending on several variables, the center may
end up higher or lower than the surrounding terrain.
Oddly enough, when these impact sites are seen
from above, they may look like the classic idea of a crater
with the center looking like a raised area, a hill or
mountain. But on examination, by moving closer and tilting
the view, the areas generally look nearly flat. This
illusion is caused by the differences in the soil types from
one area to another within the impact site.
The Navajo Impact site is one of
these. While the center is raised, the amount of rise,
compared to the length and width shows how loosely packed is
was.

Then there are other impacts, big
ones that punched a big hole in the crust of the
Earth. They let the lava flow making large
volcanoes, and the seismic waves from them formed
great valleys where large lakes formed, and the
largest of rivers flow. Often these seismic lines
are then used as political boundaries. This is the
case of Mt.
Kilimanjaro in eastern Africa. This
impact was one of a number of impacts that formed the
Great Rift Valley of eastern Africa,
and shaped a large part of the continent.
|
Then comes the problem of
size.
How big are these things?
Considering the Earth to be 8,000 miles
in diameter, and that the formula for the volume of a
sphere is:

Then 4 /3 x 3.14159 x 4000 x
4000 x 4000 = the volume of the Earth = 268,082,346,667
cubic miles.
That means that if the average
size of an object that hit the Earth was one cubic mile,
then the Earth must have been hit more than 268 Billion
times.
Or from another angle, if the earth received 1,000,000
hits,
the average size of the object must have been
268,082 cubic miles in volume,
or 80 miles in diameter.
While that may seem like a lot, if the Earth's diameter is
8,000 miles,
it would take 100 of those side by side, just
to make one diameter!
An object depositing 268,000 cubic miles of
material on the Earth would act significantly to define the
continents. That would add one mile of thickness to an area
more than 580 miles in diameter. An impact that big would
leave some pretty serious marks. Many of these objects then
would have been many times that in diameter, and by
impacting such volumes of material on the Earth, we can
start to understand how the shape of the Earth was
determined.
But now...
The probability
is that the largest impacts came first, as larger objects
have more gravitational attraction, and that was a very
long time ago. What is left for us to see on the surface
are with a few exceptions, the remains of much smaller
impacts. These impacts generally smash themselves to bits
as they hit, throwing the material of their making out
over the surface in every direction and adding a new layer to
the Earth. Or they bury themselves in the Earth.
However the shock waves they produce, in
those expanding circles, deformed the land to make the
mountains, hills, river valleys, coastlines and more for
hundreds, and sometimes thousands of miles in radius.
When we look at the
Earth for evidence of impacts, we need to be thinking on
this large scale.
We should not be aghast should someone
suggest an impact site of 1,000 or 2,000 miles diameter.
In fact, we should expect them.

Should we be worried about large
impacts today?
Our Earth came
together violently. Considering that these impacts create
shock waves that form mountains and river valleys as they
expand, and that the difference in elevations between them
is often hundreds, if not thousands of feet, a hit by one
of these would be like a circular tidal wave of solid
earth, hundreds or thousands of feet high, expanding and
reverberating at tremendous speeds. The shock waves may
expand for thousands of miles. Entire cities would be
reduced to unrecognizable rubble. Plant life could
re-root, but anything else that walks, crawls or swims
would be devastated.
As far as
mass extinctions are concerned, noxious gas plumes or dust
clouds that blocked out the sun may have happened, but
after a land wave 500 feet high passed over the
continent, gas and dust clouds would not have much
significance. And it looks like there were many,
many of these impacts.
It must be
understood that our Earth, as big as it is to us, is no
more than a tiny speck in the universe, and there are many
things out there far bigger than us. Just to orbit the
Earth requires a velocity of about 15,000 miles per hour.
These space rocks may be traveling at 25,000 to 50,000
miles per hour and more. The energy of a medium sized
asteroid hitting the Earth would be far greater than
anything man has seen before. The impact pictured above of
the Dinamita
Crater near Durango, Mexico shows circular seismic
wave alignments that deformed the ground at 950 miles
(1,525 km) distance and beyond. It is likely that if
this asteroid hit today, every building within 950 miles
of it and possibly farther would fall. These things make
earthquakes at 9 and above on the Richter scale look like
kindergarten play time.
Such was the formation of our
Earth! |
As the Earth was formed by a
bombardment of various objects, when they hit, often times
they blew the material that made them in all directions to
form sedimentary layers, one after another which built up
the planet. Every impactor was as different as the universe
that it passed through, and so each layer is as different as
that which formed it.
Interesting studies could be
made using the logs of well drillers to map out the 3
dimensional underground extents of the various soil types
encountered down into the earth. According to this theory,
the extents of the impact circles could be determined
by the extents of the various soil types described on the
well drillers logs. Maps could be made to demonstrate the
various accumulations at their depths. And perhaps, if
there was an asteroid made of gold that impacted the
earth, the extents of that impact could be mapped.
Knowledgeable well drillers of all types
should keep samples of the layers they drill through for a
chemical analysis. At some point they will drill through a
valuable layer. Once they find a valuable layer, the rest of
the impact can be mapped, and the concentrated deposits then
found.
We see in many places here on the
Earth, how minerals have come together so that we can mine
them in great quantities. Gold, for instance, will erode
down from the mountains and collect in the sand bars of the
rivers and streams to form placer deposits where miners pan
for gold. This happens because of the specific
characteristics of gold. Other minerals accumulate in
different ways because of their specific characteristics and
circumstances. If this happens here on Earth, is logical
that it happens also out in the vast reaches of space, so
that over billions of years like elements come together.
Thus, while most of the impactors
would be composed of plain old dirt like you walk over every
day, some of them could be highly concentrated with specific
minerals. Is it possible then, that some of them are made up
of gold, copper, aluminum or titanium? Could this be one
reason why minerals here on Earth are concentrated as they
are? Is this why in some places we have mines that are miles
across and go deep into the Earth? Is there a connection
between the mines we have found and impacts? If so, then
where do the minerals end up after impact?
