The Noahic Flood and The Grand Canyon. Modern Technology allows us to see with new eyes!
If you have been around for awhile, you may have found that very often the actions people take are all about them and not about you. Someone may hurt your feelings, but he was simply doing what he wanted without having given much regard to you at all. In one way that may be a bit of cold comfort for a jilted girlfriend or forgotten friend, or, it may not make you feel better at all. No matter, it is true, people have a tendency to be selfish and do what most benefits them.
I am a bit of an oddball in the eyes of the atheistic world in that there are quite a few things I do in order to please God rather than myself. But the thing is, when you get to be a Christian you actually want to please God. So it is as normal for me to want to do what God wants me to do with my life as it is for an atheist to please himself...almost. Christians still have selfish desires and we still seek comfort and pleasure and fun and all that stuff. But there is a drive to please God and an acknowledgement of the grandeur of the Almighty who is always with you in all situations?
God is not a spy or an intruder, I invited Him into my life and I want Him there at all times. After awhile the concept that God sees me at my worst, hears my innermost thoughts and fears, it leads to the complete freedom of transparency. I cannot avoid God, why would I try and with nothing to hide I can simply be myself and do what I do. In turn, it becomes more natural to be myself around all people in all situations whether work, church, store or banquet.
It really is a shame that so many people are determined to ignore the evidence and believe in a naturally occurring Universe with naturally occurring laws and life and information and etc. It doesn't matter that these things are statistically and logically impossible. It does not matter than applied science has depended upon some of the laws Darwinists reject. Believe me, if Biogenesis was NOT true, you wouldn't want to open up and eat that can of tuna you've had in the cupboard for six months!
When it comes to the Grand Canyon, the personal stakes are exceedingly high. On the one hand, the canyon is such great evidence for the Noahic Flood that it is used for college classes in Genesis Flood Science and hosts Creationist Rafting Trips as well. On the other hand, desperate Darwinists try vainly to use that same canyon to bulwark their ramshackle hypothesis before it falls over with a loud bang!
A receding Flood scenario for the origin of the Grand Canyon
Many creationist geologists have proposed
that the Grand Canyon (GC) was formed by a catastrophic dam-breach
event. This would have released large quantities of
water from impounded lakes east of the canyon that had remained on the
plateau after the Flood. This event would have carved the GC, starting
from the east moving to the west. Yet there are many
features of the GC that cannot be adequately explained by such a
dam-breach event. A better explanation is that the GC was formed while
the waters of Noah’s Flood receded from the American
continent. As this receding water flowed from east to west, the GC was
mainly carved out in the opposite direction, from west to east. This
scenario explains many characteristic and unusual
features of the GC, such as its location through the top of a ridge, its
branching structure, its numerous major and minor side canyons, its
meandering and the presence of multiple ‘outflow
points’ in its terminal escarpment.

the Grand Canyon region with an artificially raised water level. It

The arrow indicates a more logical point for a breaching event than
through the current higher point of the
Kaibab Plateau.
The breached-dam theory
Contrary to the uniformitarian view that the origin of the Grand Canyon (GC) was a slow process over 7 million years, creationists have claimed it was carved by a single catastrophic event by the breaching of an enormous natural dam. This breached-dam theory (BDT), as it is called, says that the water from two lakes lying east of the Kaibab Plateau, called Hopi Lake and Green River Lake (or Grand Lake), catastrophically carved through this higher-lying plateau and formed the GC.
Walt Brown presented an account of the BDT in his book In The Beginning, which was first published in 1980 and is now in its 8th edition.1 In the late 1980s, Edmond Holroyd defined the boundaries of the two lakes.2,3 Steve Austin et al. summarized the BDT in his 1994 book about the GC.4
Figure 1 is a Digital Elevation Model of the region around the GC and indicates by joining lines of equal contour (calculated by software) the raised water level that defines the possible outline of the lakes.5
Brown most explicitly describes the process of the dam-breaching, whereas Austin only roughly outlines the general idea of such a breach. Most often when a BDT is discussed, reference is made to other ‘canyons’ that have been catastrophically carved, such as:
- Mount St Helens canyons, which were carved following the 1980 volcanic eruption.
- The Scablands, caused by “The Lake Missoula Flood”.
- Burlingame Canyon near Walla Walla, Washington,6 caused by the drainage of storm water.

of Google Earth can help to better understand the scale of the impacts
the Flood must have had in shaping the landscapes
of the earth
Features of the Grand Canyon that need to be explained
Feature 1: The GC is carved through the higher points in the landscape
Figure 5 shows a north-south cross-section through the GC area, starting from the northern mountains on the left to the Kaibab Plateau and the GC on the right. This is the so called ‘Grand Staircase’. It can be seen that the GC cuts through the higher parts of the Kaibab Plateau on the right and not through the lower level near the Chocolate Cliffs in the middle, which roughly corresponds with the area in figure 1 indicated with the arrow. Why would any breaching occur in a higher part right through a ‘mountain’ rather than in a lower part?
Figure 5. A north-south cross-section
through the so called ‘Grand Staircase’ illustrating the geological
strata that comprise the walls of the Grand
Canyon, which is at the far right.
Because the continents are being compressed and the ocean basins are sinking, the area of the Colorado Plateau is uplifted and therefore the water within the GC Inner Sea is retreating in a westward direction and the water-level is lowering. The water follows many routes flowing out of the area from higher to lower regions. When there is a submerged landform, such as a plateau, mountain, hill or ‘sandbank’, the water will not only flow to the left and right of the landform but also over its top as long as it remains submerged. The water flowing over the top will, at a certain point, increase in speed, since there is less and less room for the water to find a way. Therefore some parts of the top of the landform will start to erode faster than other parts or the sides. In this way a channel or gully will form right through the higher parts of the elevation
(figure 6).
Figure 6. Schematic of how a canyon is
carved through higher ground as water levels lower (phases 1–5). Image B
is a cross-section of image A at the vertical
dotted line. When the water in image A flows from right to left over a
submerged elevation it may carve out a gully in the elevation (image B),
even though water still flows at the sides.
As the gully deepens, it grows in the opposite direction of the water
flow (image A).

Figure 7. The Wadden Sea in the
Netherlands, a tidal area with sandbanks, illustrates how the daily
tides cut through the higher points in the sandbanks to allow
the retreating seawater to pass.
|
As the water level keeps falling, the sides of this initial channel will emerge from the water (phase 1 in figure 6). But water will continue to flow rapidly because of the enormous volume of water that still needs to drain out. The underwater mountain hinders the receding water and therefore the water will take every possible route out. Thus the channel will be carved deeper and deeper, even though there might still be water flowing along the sides of the elevated landform. Provided the water level of the Inner Sea lowers slowly enough, water will keep flowing through the channel and erode it deeper and deeper as the water level lowers (figure 6B). As a result, the channel will grow longer in an upstream direction, beginning in the area where the landform is highest and moving to the area where the landform is lower. The most remarkable thing about this process is that the direction in which the gully is carved is opposite to the direction the water flows (figure 6A).
Another remarkable feature of this drainage process is that, once the channel has achieved a certain length, it will start to branch out like a tree as the water continues to drain from the plateau. The main channel will develop side channels, which in turn will develop side channels, and so on. The side channels develop because, as the main channel grows in length, the water on the plateau is then able to flow sideways into the channel. This sideways flow eventually initiates secondary channels that continue to grow sideways (Feature 2 and 6).
It is possible to see today how this process produces a branching structure by observing tidal areas with lots of sand, such as in the Wadden Sea to the north-west of the Netherlands. Gullies are cut by the daily tides through the a submerged landform, such as a plateau, mountain, hill or ‘sandbank’, the water will not only flow to the left and right of the landform but also over its top as long as it remains submerged. The water flowing over the top will, at a certain point, increase in speed, since there is less and less room for the water to find a way. Therefore some parts of the top of the landform will start to erode faster than other parts or the sides. In this way a channel or gully will higher points in the sandbanks to allow the retreating seawater to pass through. Figure 7 shows an example of this effect in the Wadden Sea. The lighter coloured areas are already dry. The dotted line indicates the higher point of the sandbank. The large black arrows indicate the direction of the flowing seawater when the sandbank is submerged. It can be clearly seen how several gullies have been cut through the higher levels (the narrow white arrows pointing upward in the foreground) and branch out in the lower levels that are still underwater in this picture (the narrow white arrows pointing downward in the middle). The structure of these gullies is not exactly the same as in the GC, but this is likely due to:
- The scale of the GC, which is more than an order of magnitude larger.
- The amount of water flowing through these gullies, which is many orders of magnitude less than in case of the GC.
- The GC having been a one-time event, with maybe some limited tidal effects. The sandbanks and gullies of the Wadden Sea are the result of long periods of tides, day in and day out.
Feature 2: The branching structure of the western half of the GC

western part of the Grand Canyon. Branches are shaped as a V or U with
the width tapering away from the outlet of the
branch. The branching shapes on branching shapes resemble fractals.
|
Figure 9. The Niagara Falls illustrates
how steady erosion by a constant flow of water produces a U shape.
Erosion of the Falls is in the opposite
direction to the flow of water.
|
Figure 8 shows the typical branching structure apparent along the western part of the GC. The dotted line indicates one side or ‘bank’ of the GC. At several positions branches can be observed extending away from the GC and these branches become narrower as they extend further away. This narrowing means the edges of these branches tend to have a triangular shape. The branches themselves also have branches, and those might even split further. The edges of the branches always seem to be shaped as a V or a U. A ‘sudden’ high-velocity current caused by a dambreach would carve out parallel channel-like structures, as can be observed in the Scablands (figure 4). It would not create this sort of branching pattern, nor would it create these V- and U-shaped gullies.
A spectacular example of such similar V- or U-shaped erosion on an escarpment, which is still eroding up to this present time, is the notch of the Niagara Falls (figure 9). This shows that a relatively constant supply of low velocity water on the plateau can explain the origin of a V- or U-shape better than a breach event can. Notice also that the Niagara Falls is eroding backward in the opposite direction to the water flow, as discussed previously with figure 6. Once the V-shape of the main canyon is established, three conditions are needed to form the typical branching type canyons observed in the GC:
- There needs to be a relatively constant (or regular) supply of a large volume of water covering the raised area and flowing into the main canyon.
- The raised area/plateau needs to be rather flat so the water can flow into the main canyon from both sides. The steeper the downstream slope on the raised area, the shorter and narrower the V-shape of the main canyon will be. When the raised area is flat, it will result in a main canyon with a long, broad V and with more branching.
- The sediments need to be relatively soft; otherwise the erosion would be too slow to keep pace with the lowering water level. In hard rock the water would have flowed away over the sides of the raised area before any gully/canyon had time to be eroded.

Figure 10. Branching type channels on the coast of Argentina have an appearance similar to the branching in the Grand Canyon.
The much deeper channels in the middle of the GC were formed after the main canyon was cut, and they are still being eroded today by the normal drainage of the Colorado River that flows through it (see feature 5, p. 111).
Along the coast of Argentina we can also find beautiful examples of branching structures caused by receding tidal water as shown in figure 10. Note the similarity of the wide flat mud flats, cut by the narrow gully in the middle, with the features of the GC. Also note the steeper ‘cliffs’ on the sides and the branching ‘canyons’ towards the lower-lying parts behind the cliffs.
Feature 3: The non-branching structure of the eastern half of the GC
As shown in figure 2, the eastern part of the GC northwest of the Kaibab Plateau does not exhibit the branching structure evident in the western part. On the North Rim, the canyon shows a typical erosion pattern that can also be observed in mountainous areas. The cliffs located on the South Rim look much like a collection of landslides that slipped into the GC. These features indicate that the process that formed the eastern part of the GC is likely different from the process that formed the branching part in the west. It suggests that the GC was formed in two major steps, a western step and an eastern step. Both steps would have initially involved cutting through higher ground—one through the Kaibab Plateau and one through the Hualapai Plateau (see feature 4 below). Both would likely have been formed at the same time. However, the western arm would eventually extend to connect to the eastern Kaibab section when the water level had lowered enough.
Neither the BDT nor the regular uniformitarian views can adequately explain these differences.
Feature 4: The multiple ‘outflow points’ at the end of the GC
Image generated by Google EarthTM 2007; DigitalGlobe 2008.
Figure 11. The westward end of the Grand
Canyon looking east across the escarpment to the Hualapai Plateau.
Apart from the outflow point of the Grand Canyon (point
number 5), there are a number of similar but smaller ‘outflow’ points
(numbered 1 to 4 and 6 and 7).
However, there are several other ‘outflow points’, or gorges, cut back into the escarpment. Although they are smaller than the GC, they have a similar appearance. Markers 1 to 4 identify some of these smaller outlets in the vicinity of the GC. These gullies/ canyons are not currently operating as drainage outlets for the catchment area behind them. Marker 6 identifies another such outlet, which is currently operating as a drainage outlet. Marker 7 is on the other side of the GC at another outlet, and this one is even harder to explain in terms of being formed by the present drainage system because the GC is right behind it and takes care of all the drainage.
The elevation of the entire plateau area surrounding the GC rises slowly as we move downstream along the GC from east to west, forming a ridge. The elevation of the plateau ‘suddenly’ drops off at the ridge/escarpment mentioned above. Figure 12 is a view south along this escarpment, with the high plateau to the left and the lower landscape to the right.
Image generated by Google EarthTM 2008
Figure 12. Looking south across the
Hualapai Plateau, showing the same outflow points numbered in figure 11
which are eroded as gorges into the escarpment. The
receding floodwaters flowed from east to west, i.e. from left to right.
As the water level dropped, only one of those outflow points (probably the longest and deepest at that time) continued to flow, whereas the others ceased to serve as outlets. Outflow point number 5 in the Hualapai Plateau remained in service to drain the rest of the water behind it and, as such, continued to erode deeper and further eastward. This is an example of cutting through higher ground similar to that which we saw with the Kaibab Plateau.
Different erosion patterns on the north and south rim of the GC outlet
Allen Roy concluded that a ‘recent gigantic flood’ eroded the Hualapai Plateau.8 An outflow point, as described above, fits this observation very well. Strangely enough, branching, V-shaped structures are not present on the southern side of this GC outflow point as they are on the northern side. When we examine the landscape, we can see that this must have been because the northern parts served as outflow points for the higher northwest region of the plateau, but the southern parts did not need to drain the lower southern area. They served as a bend in the miles-wide ‘river’ mouth of the receding water (see figure 15) and thus more smoothly eroded the Hualapai Plateau there.
At the most southerly point (at the ‘question mark’ in figure 15, called Peach Springs) there might even have been another second large, but temporary, outflow point for this GC ‘river’.
Figure 13. Schematic cross-section of
the Grand Canyon, showing the dual structure: section A, which is wide
and shallow, and section B, which is narrow and
deep.
Feature 5: The dual cross-section of the GC
As shown in figure 13, the cross-section of the GC has two distinct shapes. The canyon of section A is broad and relatively shallow. The canyon of section B sits in the middle of section A. It is much narrower, is carved much deeper and has steeper sides.
The Colorado River flows through section B. The present size of the Colorado River is a good fit with the size of this deeper canyon, indicating that this deeper section was eroded by the Colorado River over time. It also means that the flow in the Colorado River in the past (when the narrow canyon first began eroding) was similar to the flow in the river at the present time.
However, the broader section, A, could not have been eroded by a river with the same size and flow as the Colorado River. It would have had to have been eroded by a river with an immensely larger volume of flow. Using Google Earth, we can estimate the size of the ‘river’ and superimpose it on the map (figure 14 and figure 15). By connecting all the sides/banks of the GC (ignoring the side canyons), we can see this is an immense river of unparalleled scale. We may conclude that this broad river represents the Flood drainage-river that carved the section-A portion of the GC.

Grand Canyon are connected (ignoring the side canyons), the magnitude of
the initial water channel that carved the canyon
becomes
clear. The channel is much broader at its mouth (to the left of the
figure in the west) than upstream toward its source (to the right in the
east). This whole ‘river’ is
basically another V-shape.
|
This dual cross-section indicates that the initial volume of water flowing through the GC outlet point must have been huge. When the water level lowered, its volume decreased, creating a narrower river and eroding a narrower channel in the lower parts.
The deeper canyon (figure 13 section B) in the middle of the broad canyon (section A) only started to erode after all the floodwater on the plateau has drained. It was eroded by the normal drainage of the huge Colorado basin, which continued to flow through section A. Erosion at this reduced scale continues up to the present day.
Feature 6: The large side ‘arms’ of the GC
The GC has two very large side canyons visible in the middle of figure 2, one extending north and the other south. It also has several smaller side arms on its western part. The larger branch in the north is called Kanab Canyon and the one in the south is called Havasu Canyon. Those side arms themselves also exhibit the typical branching, V-shaped structure. They are broad where they join the GC and narrow at their extremities. On first impression, these branches look like drainage systems for the catchment area they are located in, not like channels caused by a sudden flood of water from the east. The side branches are perpendicular to the direction of the main part of the GC, which means they cannot have been formed by a dam-breach event. A dam breach releasing water from behind the Kaibab Plateau would have carved canyons in the direction of flow, as illustrated in figure 4, not perpendicular to it.
However, these side branches are beautifully explained by the RFS. These canyons would have formed in a similar way to the rest of the GC but after much of the CG Inner Sea had drained from the plateau. The side branches extend into regions where there were still huge amounts of water that still needed to drain. The only way these enormous amounts of water could drain was to the lowest point in that area, which was toward the GC channel.
We can simulate the water flows at the time the floodwaters receded by ‘lowering’ the water level in the GC region using software and a Digital Elevation Model. Figure 16 shows a sequence of six steps as the water level drops, making it clear what areas of the landscape emerge and what areas remain underwater at subsequent stages.
Figure 16. Simulation of the Grand
Canyon region as the water level lowered. The white lines indicate local
elevations by which the huge northern and southern lakes
are separated from the Grand Canyon. Arrow A shows where the northern
lake connects to the Grand Canyon. Arrow B indicates the direction of
water flow from the northern lake as it carved
Kanab Canyon. Arrow C shows the direction in which Kanab Canyon was
carved as the water lowered and the northern lake emptied.
We need to take into consideration that a lot of water from the northeastern part of the Colorado Plateau also would have found its way through Kanab Canyon until the water level was so low that the gap north of Kaibab Plateau at Chocolate Cliffs (arrow in figure 1) was closed.
The Havasu Canyon to the south only shows a lake in the first picture of figure 16. It does not show a diminishing lake at its very tip as occurs with Kanab Canyon. This may suggest that Havasu Canyon would have formed differently or much quicker than Kanab Canyon. Yet, it is the larger of the two and it still has exactly the same patterns. Therefore it seems justified to conclude that there might have been some relative tilting of the southern part compared to the northern part after the canyon was created.
Figure 17. Possible temporary situation
where two large northern and southern lakes drain their contents into
the Grand Canyon. The arrows indicate the location of
the initial waterfalls which carved backwards to excavate the side
canyons as the lakes emptied.
To compensate for the possible tilting of the southern part and to make a more accurate estimation of the situation with the side arm lakes, figure 17 has been created. This figure illustrates how that, as the water level was lowering and the GC ‘river’ was diminishing, two lakes formed on the plateau, one trapped to the north and the other to the south. These lakes released their water into the side branches of the GC in the same way that the GC Inner Sea earlier flowed into the GC on the Hualapai Plateau. At the overflow points of these lakes (indicated with the arrows) waterfalls like the Niagara Falls, but much larger in size, were carving both side canyons at the same time.
Feature 7: The Colorado River is meandering at Marble Canyon
Image generated by Google EarthTM 2008
Figure 18. In Marble Canyon the Colorado
River meanders through hard rock, which is impossible. The arrows
indicate branches that face upstream against the flow of
the Colorado River.
One prerequisite for a river to meander is that the sediments it flows across are soft, not hard. Meandering is caused by a combination of erosion and deposition of sediments. What could possibly explain that the Colorado River is meandering in hard rock? The likely answer to this would be that such rock wasn’t that hard when the Colorado River originally carved its first shape.
Another prerequisite for meandering is that the water has to flow slowly enough to deposit the sediments. Therefore the BDT is not adequate to explain this, but the RFS is.
The uniformitarian explanation for this feature is that the river first formed in deposited alluvium and that after uplift of the Colorado Plateau it continued eroding down through the hard rock.10-15 Nevertheless, at Marble Canyon there is no alluvium on the plateau, neither is there any trace of a previous alluvium.
Figure 19 is an example of meandering gullies caused by receding tidal water in Wadden Sea. It clearly demonstrates that slowly receding waters are well capable of creating meandering structures. This means receding Flood water is the best explanation for the meandering Colorado River at the level of Marble Canyon.

Feature 8: Some branching canyons in Marble Canyon point in the opposite direction
Some of the side canyons of the Colorado River in Marble Canyon point upstream to the river instead of the normal downstream direction (see arrows in figure 18). Brown1 tries to use this as evidence for a dam-breach theory, but a more logical explanation is provided by the RFS. The level of the rim of Marble Canyon and the surrounding plateau slopes ‘uphill’ against the direction of the flow of the Colorado River. Of course the river doesn’t flow uphill, but it does cut through higher ground and therefore the rim becomes higher as we go downstream. The reason that the Colorado River flows through an uphill area is the same reason that explains the other parts of the Colorado River: receding waters cut it out. Therefore the side arms connecting to the Colorado River point in their logical direction: downhill to the east, which happens to be in upstream direction of the Colorado River that now flows to the west.
The Receding Floodwater Scenario
We cannot be completely certain of the precise extent and size of the drainage basin, the GC Inner Sea, that emptied through the area of the GC because, for instance, there has been compression in the north of the region and the Colorado Plateau has been uplifted. Nevertheless a rough impression of its size can be made by following the current higher mountains as its borders (hatched area, figure 20). However, the current drainage system of the Colorado River extends even further north beyond the borders of the map. It is possible that there might have been another continental sea of similar size, the water of which eventually also found its way out through the GC area (plain area, figure 20).
Figure 20. Possible extent of
temporarily impounded water on the western part of the continent forming
an inland ‘sea’ that drained through the Grand
Canyon into the ocean.
There is something to say for simultaneously cutting the canyon at two locations. Because the Kaibab Plateau is also at a high point in the landscape, the carving process should have begun there before the lower side arms began to form. This means that there might have been a western and an eastern part of the GC that only interconnected later on when the water was low enough. We have to take into account that the region has been uplifted. This would have been caused, not only by tectonic compression, but also the removal of the weight of water resting upon it.
As with any model, the RFS is based on certain assumptions. The first, of course, is that the entire region, and thus the whole American continent, was fully covered by water. It also assumes that any continental movement associated with the concept of plate tectonics happened quickly, over weeks and months, during the year of the Flood (as in the Runaway Subduction Model). In addition, the consequent compression of the western part of the American continent probably was nearly almost finished by the time the waters started to recede.
These considerations result in the following scenario:
- As the floodwaters were receding the GC likely started eroding at the two higher points in the landscape, first in the east (Kaibab Plateau), since that was probably higher than in the west (Hualapai Plateau). At this point all the sediments, which were deposited earlier in the Flood, were still soft and wet and not hardened rock.
- On the escarpment/ridge to the west some 5 to 7 overflow points developed simultaneously as the waters receded. One of these points carved further, faster and deeper and therefore remained to serve as an outflow for the GC Inner Sea that became trapped on the continent behind the ridge. The other overflow points stopped releasing water as the level dropped.
- The upper cliffs of the borders of the western Grand Canyon are former waterfalls that drained the water of the GC Inner Sea into the GC and created the branching structures. These waterfalls were relatively short lived. At this time the ‘Grand Canyon’ was a huge ‘river’ kilometres wide.
- When the southern Havasu and northern Kanab side arms where cut, the waters that kept flowing through the Kaibab outflow carved a connection with the main system, thus establishing almost the entire length of the GC.
- Eventually, Marble Canyon was cut out by the waters trapped behind the Kaibab Plateau after its level was so low that it was not able to flow through the northern opening anymore.
- During the process the entire area was gradually lifted up, partly because tectonic forces where compressing the continent, and partly because the weight of its Inner Sea was decreasing, resulting in isostatic adjustment of the continent.
- In the ages after the Flood, the sediments dried out and hardened to solid rock. The Colorado River continues to flow through the GC but is a magnitude smaller than the GC ‘river’ that drained the receding floodwater. Therefore the rate and pattern of erosion dramatically changed compared to what it had been initially, carving the narrower, deeper and steeper, inner canyon. More ‘normal’ post-Flood weathering and smaller-scale drainage erosion has also extended the borders and cliffs of the GC but only in a relatively small measure.
Conclusions
There are a number of unusual and characteristic features of the GC that need to be explained by any model for its origin. These features include the branching structure of the western half of the GC, its numerous major and minor side canyons, and the location of the canyon in the higher parts of the region. Other unusual characteristics of the GC include the meandering parts of the Colorado River and the existence of multiple ‘outflow points’ from the escarpment, some of which are now ‘dried up’.
These characteristic features of the GC also run counter to a sudden draining of post-Flood lakes in a dam-breaching event.
These characteristic features of the GC also run counter to a sudden draining of post-Flood lakes in a dam-breaching event.
A Receding Flood Scenario, whereby the North American continent was once covered by water kilometres deep that needed a way out after becoming trapped in a gigantic bowl when the area was uplifted, is a relatively simple model that incorporates and explains all of these features elegantly. The volume and extent of the water that drained was of a scale even larger than the entire GC itself and the processes involved are hard to research or even imagine without satellite images and modern software.

Dear Dr Scheele
Your arguments are very persuasive.
Does Google Earth also suggest where the massive amounts of material exiting the mouth of the GC ended up? Is there evidence of this on the US west coast?
Tas Walker responds:
A good place to look for the material is on geological maps, although it seems like the receding waters mainly took the material out of the region.
Brian L., United States, 4 May 2012
Excellent Article! This would make a great DVD showing a simulation of the water flows and the consequential changes in the terrain that could be sold in the Creation.com store.
Tas Walker responds:
Thanks. And the error you also mentioned has been fixed.
Susan W., United States, 5 May 2012
Great article, I was curious if there was a missing word in one of the sentences. The article states "In this way a channel or gully will (?missing word?) higher points in the sandbanks to allow the retreating water to pass through". I don't read geological articles at all except for your site, so maybe it is just me, but it seems that a word like possibly "erode" belongs there. It would help me to understand the article if you could explain that sentence to me, thanks for such an interesting discussion, God Bless you!
