So this "local flood" not only produced the grand canyon but landed Noah half way around the world in the Middle East?
No, what I'm saying is, through the study of the stratigraphy of the Grand Canyon, it becomes a strong source that actually disproves that the flood was global. Sorry, I guess the way I phrased that was a bit confusing.
The YEC/global flood proponents like to say that the Grand Canyon is proof of a world-wide flood, but the fossils found in it and also the nature of certain sedimentary layers actually end up showing the exact opposite, but formation over billions if not millions of years.
I submit the Coconino Sandstone as one such example. The vast majority of geologists who have actually been to the Grand Canyon and studied it have determined it was formed by wind, and not by water.

Also, to keep this brief, here's a summary of different fossils found in the varying layers, from top to bottom, from the website here:
http://www.bobspixels.com/kaibab.org/geology/gc_layer.htm
Kaibab Limestone: Fossils that can be found in this layer are
brachiopods,
coral,
mollusks,
sea lilies, worms and fish teeth.
Toroweap Formation: This layer averages about 255 million years old and is composed of pretty much the same material as the Kaibab Limestone above. It is darker in color, ranging from yellow to grey, and contains a similar fossil history.
Coconino Sandstone: No skeletal fossils have yet to be found but numerous
invertebrate tracks and fossilized burrows do exist.
Hermit Shale: Fossils to be found in this layer consist of ferns, conifers and other plants, as well as some fossilized tracks of reptiles and amphibians.
Supai Formation: Numerous fossils of amphibians, reptiles and terrestrial plants exist in the eastern portion which are replaced by marine fossils as you move westward.
Redwall Limestone: Numerous marine fossils can be found in the Redwall Limestone including brachiopods, clams, snails, corals, fish and trilobites. Many caves and arches can also be seen in the Redwall.
Temple Butte Limestone: The only fossils to be found in the eastern region are bony plates that once belonged to freshwater fish. In the western region there are numerous marine fossils.
Tonto Group (3 layers):
1. Muav Limestone: Its color is grey and it does not have much in the way of fossils, some trilobites and brachiopods.
2. Bright Angel Shale: Fossils to be found in this layer consist of marine animals such as trilobites and brachiopods.
3. Tapeats Sandstone: The color of this layer is dark brown and it contains fossils of trilobites. brachiopods, and trilobite trails.
Those are just a few of the many layers within the Grand Canyon. I highly recommend checking out the rest of that webpage I listed.
I'd also check out this webpage, which shows the southwestern US and the numerous retreats and advances of the sea:

There are numerous graphics, but I found it to be absolutely fascinating.
