Did you know that when Mt. St. Helens exploded, megatons of mud from a variety of rock types was projected in one direction? These layers created a gigantic natural dam on a river nearby.

The river continued to fill behind the mud dam until it crested. When it crested it began quickly eroding the layers of newly layered mud.

Today there is a canyon there that is many hundreds of feet deep. It remarkably resembles the Grand Canyon (Layers of sedimentary mud of a variety of rock types appearing to be millions or billions of years old).

So you are OK when the scientific and journalistic community’s purposefully ignores these kinds of discoveries.

Ping.

Are you attempting to suggest that the Grand Canyon was formed by a similar process? Because, I would expect that evidence of such would be clearly present in the geologic record. At the very least, one would require a volcano in some proximity to the Grand Canyon....

Have you considered that all this evidence manages to establish is that the process of water erosion in Washington State functions in a similar fashion to that same process in Arizona..

resembles the Grand Canyon

When you sa it "resembles" I assume it means it contains layers that will show they formed over millions of years, based on the age of the layers. Or do you mean "resembles" as in morons can't see any difference?

Hmmmm... My last comment may appear ambiguous, so allow me to clarify. The first process I allude to is rapid canyon formation by a torrent of water released subsequent the breach of an earthen dam created by volcanic activity. The second process I refer to is the creation of geographic features via water erosion - under whatever circumstances.

I suppose a sliced layer cake resembles the Grand Canyon too. Of course, in the strat of the earth we also find a progression of life forms in the rock strata -- which we don't find in newly formed mud layers or in our layer cakes. But I suppose that is a mere trifle.

No one who says this with a straight face knows what he or she is talking about. It's just nuts.

Every layer in the real geologic column of the Grand Canyon is a distinct ecosystem. From here we have the following:

Flood Geology and the Grand Canyon - Grand Staircase

Precambrian Strata

Paleozoic Strata

Triassic Strata

Jurassic - Cenozoic Strata

Conclusion

I hope you'll give it the attention it deserves, as you have a few problems with the evidence.

When it crested it began quickly eroding the layers of newly layered mud.

Sediments deposited by Mt. St. Helens are not only one formation, but they are also unlithified...therefore very easy to quickly erode.

The Grand Canyon, however, is composed of many lithified formations and is tough to erode. Translation: Rocky formations take much longer to erode than simple sediment.

Except that much of the rock in the Grand Canyon isn't soft sedimentary; it won't just "wash away" in a flood of water. A lot of of heavy metal mining (tungsten, uranium, etc) has been done inside the Grand Canyon from the metamorphic and igneous layers that make up its geology. To erode these types of layers to a level that deep requires extraordinary amounts of time. Extrapolating from a mud-n-ash dam in Washington is specious reasoning.
