The Canadian Shield
Northeastern Canada is fractured and
scoured down to bedrock in many places with almost no
vegetation growing. Thousands of lakes and rivers inhabit
channels that appear to have been carved first and then
adopted by them.
Whenever Spring returns to the Northern Hemisphere, the Maritime Provinces of
Canada continue in frozen hibernation, melting slowly because the exposed
bedrock does not warm up quickly in the sunlight.
Nearly the entire
eastern half of Canada, including Hudson Bay and the Great Lakes, is
composed of criss-cross fracture lines, deep rifts, loose piles of gravel and
pebbles that extend for hundreds of kilometers, and
parallel ridges with lakes between them that have no outlets. The landscape
is said to date from the end of the last Ice Age some 15,000 years ago when
glaciers moved across North America in sheets covering the continent. The
inexorable weight of the ice ground down the surface topography and left gouges
and grooves in the rock while it pushed the debris ahead of itself or carried it
away in suspension, dropping the material far from its origin when the ice
In a previous Picture of the Day article about the Manicouagan Impact Structure
in Canada, the unique geography in the region was explained by the action of
electric arcs machining down into the rock strata, leaving circular formations
and sinuous rilles as evidence for their explosive passage through the layers.
The lack of debris in the crater, vertical sidewalls, the shallow, flat bottom
and glassified breccias were also considered to be evidence that supports an
electric arc theory better than most theories of glacial erosion.
The term "shield" comes from the fact that the area looks like a Viking shield
although it is more of a
horseshoe-shape, overall, considering Hudson Bay and the outlet to the sea.
Gold, copper and nickel mines are scattered throughout the Northwest Territories
and Kimberlite pipes have also been exploited for diamonds, making the
mineralogical composition similar in many ways to Siberia where
another crater the same size as Manicouagan can be found.
Observations from the
Canadian Shield seem to add additional support for electricity as a possible
formative agent in North American geography and not just the movement of ice and
volcanic eruptions. Asteroid impacts are proposed when features such as
Manicouagan are discussed since there are no other alternatives for most
geologists to consider. The catastrophic origin of some landforms is
acknowledged in most circles but the electrical component is never given any
thought since the arrival of a giant rock from space seems more preferable than
the arrival of a giant lightning bolt from space. This attitude demonstrates a
bias toward familiar ideas since we now know that small lightning bolts from
space (sprites) arrive more often than small meteoroids from space.
If the lakes with no outlets have been in existence since the end of the last
Ice Age and they presumably filled with melt water, why are their shores bedrock
with thin soils and not much sediment on their bottoms? The ice should have left
tons of sediments behind when it melted away. If the melting ice left giant
piles of gravel across the flat plains when it melted, why not on the bottom of
deep depressions that are now lakes? Did the ice not contain any debris over so
large an area?
How does ice leave marks that cross over and under each other? The fault lines
that cover the Canadian Shield are often at ninety degrees to one another and
the resulting lakes are square-shaped cutouts in the stone. There are also some
triangular lakes because the fractures meet at a forty-five degree angle. Did
the ice sheets change direction as they pressed down on the land in their
Craters like Pingualuit are punched into the terrain at intervals, as well:
once again, bowl-shaped, steep-walled, with no localized debris field and no
deep sedimentary deposits on the bottom.
The focus of an ion beam large enough to cut out and take away sedimentary
deposits weighing billions of tons is not easy to contemplate. The energy
requirement is so great that there appears to be no way that it can be generated
what could launch a bolt of lightning that powerful? Indeed, what could launch
hundreds or thousands of such bolts?
The surface of our planet bears witness to catastrophic events in the not so
remote past, despite uniformitarian views that assume slow, steady effects.
Craters are declared to be ancient and not recent. Mountain ranges and
valleys are asserted to be older than the memory of man and not newly minted out
of a destroyed and remade previous world, despite the mythology and folk tales
that relate eyewitness accounts how and when it was minted.
However, if we look outward we can see that our planetary neighbors also bear
the scars of forces that are difficult to explain. The moons that circle them
are half-melted balls of slag peppered with hexagonal craters and scarps 10
kilometers high that cut through other terrain like a hot knife.
There are millions of asteroids of varying sizes and the ones that have been
observed closely bear similar markings. From planetoids like Ceres down to beads
the size of a pinhead, craters and cracks are found in glassified blobs that
appear to have been put through a blast furnace. The same glassified spherules
with the same appearance as the ones collected from the Moon, for example, are
scattered all over the Earth. The shocked spherules of crystal that are found
inside meteorites are of similar appearance.
Is there a way to explain so many observational similarities in so many
environments at so many scales? That is one crucial issue that the Electric
Universe hypothesis continues to explore.
