Author Topic:   YECs, how do you explain meandering canyons?

One of the things that disproves YEC Flood "geology" is meandering
canyons. Meanders, as most of you surely know, are formed by rivers: they have a tendency to twist and turn. Mainstream geology explains the Grand Canyon as a river which had meandered which had the land which it was on uplifted forming canyons. These canyons have ancient meanders frozen in place. If a Flood quickly formed Grand Canyon and other canyons, they would not meander.
A simple look at the map shows that the Grand Canyon and other canyons formed by the Colorado and its tributaries will show that they do indeed meander. Given that YECs claim that all of this was formed via the Noachian Deluge, an explanation from the YECs of just how these meadering canyons formed is in order.
Indeed the meadering gets quite spectacular at places.
For example, the Goosenecks on the San Juan River which is a tributary of the Colorado has an incredible series of closely packed meanders in a canyon over 1000 feet high.

Another one is Horseshoe Bend on the Colorado River a bit upstream from the Grand Canyon National Park:

So YECs, what is the explanation? Any "explanation" for the Grand Canyon must also be able to explain these.

A resource on why rivers meander might be useful for this topic.
Why do rivers follow lazy loops and bends?

Re: A simple answer.
Slow rising lands NEVER form meanders. Who told you that? The meanders were in place prior to uplift, which is also required for your model, though you failed to touch on that aspect.
I thought that rising land was needed to form the deeply incised meanders.
Put the emphasis on "deeply insised." The meanders themselves will only form on fairly level slow moving river. Once the land rises, the process of meandering stops and the eroding of the canyon
begins following the "fossil" meanders.
(Also it was established in a talk.origins thread on this subject
that land going down downstream can also dig out canyons much like waterfalls moving slowly upstream over time. That does not help the YECs though...)

Re: A simple answer.
Walt Brown is just plain wrong. It does not matter what the alleged catastophic flood is the Noachian Deluge or a dam burst, it will not create a meander.
And if such a catastophic flood caused the Grand Canyon than how come it failed to do anything to the land immediate outside of it. One of the things that is so striking about visiting Grand Canyon is until one actually sites the canyon itself, there is no sign (well other than "Grand Canyon x miles" etc) that anything geologically unusual is in the area. How can a catastophic flood be so precise?

Re: A simple answer.
Have you considered my message 14 possibility?
It is NOT a possiblity.
Meanders will ONLY appear on a relatively level river course. A flood capable of digging out something as large as a canyon is not going to follow such a shallow meanders.
Unless you are willing to invoke a miracle, the Grand Canyon was formed by a river, and not a flood.

Satellite Views
One can really see the meandering nature of the Grand Canyon and the rest of the Colorado river/canyon system using Google maps.
Dragging these images to see more terrain. One can also zoom in and out.

I have nominated an image of the Goosenecks of the San Juan River discussed at the start of this thread for Wikipedia Featured Picture. Those wishing to comment on the nomination can do so by following the link.

I have not added examples in a while:
The confluence of the Colorado and Green rivers:
Image source which includes a nice photo of Goosenecks from a different perspective than earlier in this thread.
Of course the question still stands: how can a YEC explain a meandering canyon. Recall the floods do not meander.
