Fluvial stratigraphic columns – a study of  arizona

The depositional process uses well-rounded gravel, course gravel of the Mogollon Rim in Northern and Central Arizona, called rim gravel which was examined at two separate and widely respected locations for this study.

Literature gave further information regarding the rim or course gravel. The gravel is very course near the East-Central portions of Arizona and the course gravel is occupies the uppermost terrain in the region. 

It has been found that the course gravel was deposited as a sheet it eroded into small pieces during the Recessional Stage of the Genesis Flood. A consensus was met that the Rim Gravel provides the facts that the Flood and post Flood borders match up with the stratigraphic location of the rock which has been named “late Cenozoic” in this uniformitarian geological column in the Western part of the Untied States.

Many formations of geomorphic features, including such wonders as the Grand Canyon of the Colorado River which makes this interpretation relevant to these theories.

Gravel that is coarse on top of the Mogollon Rim in the Northern and Central Arizona is called the rim Gravel and has a great significance for questions of historical geology in the American Southwest. The coarse gravel occupies an erosion surface on the highest terrain in East-Central Rim. The course gravel occupies an erosion surface on the highest terrain in the region and is believed to have once been continuous along the Rim.

A large percentage of the gravel is an exotic quartzites, sometimes with percussion marks. Based on literature sources, paleocurrent data indicate the coarse gravel was transported from the west and the south that currently is at a much lower elevation than the Mogollon Rim. Some of the Paleohydrological analysis has given us calculations that the coarse gravel was transported by sheet flow moving at a rate of at least a few tens of meters per second – about 40 mph or greater.

However, the uniformitarian age of the gravel is generally believed to have been early ‘Cenozoic,” it can be surmised that the gravel and the “Mogollon Highlands” to the south were eroded probably in the mid “Cenozoic” era. If the erosion for the area is more channelized, it would probably be assigned to the late “Cenozoic” era. This is based on the assumption that these uniformitarian classifications have any real meaning at all.    

We conclude that this coarse gravel was deposited as a sheet during the early Recessional Stage of the Genesis Flood. The area then underwent erosion of the deposited gravel and substrate during uplift of the area, generally during the Channelized Phase of the Deluge.

We can then infer that the Rim Gravel provides evidence that the Flood and post-Flood boundary largely corresponds to the stratigraphic location of rocks termed “late Cenozoic” in the uniformitarian geological column in this part of Western United States.

And since the Grand Canyon of the Colorado Rivercuts through the Rim Gravel, this characteristic must post-date the deposition of the Rim Gravel at least slightly.
