Two separate research reports arrived at a similar conclusion.1,2 Both found an episode of mysterious erosion had occurred near the end of the Tejas Megasequence. This event likely correlates to the final phase of water draining off the continents during the Flood. It also confirms a late Cenozoic end of the Flood boundary, called the N-Q (Neogene-Quaternary).3,4

The upper subdivisions of the geologic column with the N-Q and the K-Pg boundaries identified The first study examined river systems upstream from Grand Canyon. The study area was primarily in southeastern Utah and included the Colorado River as it passes through Glen Canyon, Cataract Canyon, and Meander Canyon. This area is known as the central Colorado Plateau, a broad uplift that rose about 5,000 feet during the Cenozoic (Tejas Megasequence).

The study team led by Natalie Tanski, who’s now at the University of Oklahoma, discovered that river incision paused in the early to middle Pleistocene (Ice Age) and was followed by a brief period of rapid incision in the late Pleistocene to the present. They speculated that this hiatus in erosion “may record a planated [smoothed at one elevation] landscape prior to the propagation of baselevel fall from Colorado River integration.”1

They further noted that this recent river incision only accounts for about 200 meters (650 feet) of the total erosion off the central Colorado Plateau. The team concluded, “This requires an unknown driver of significant ~ Pliocene exhumation [erosion] of the central Colorado Plateau that is not linked to Colorado River integration [later stream development by incision].”1 They added, “The driver for the older, Pliocene erosion [~2 km or 1.25 mi] of the landscape recorded by thermochronology, and where that eroded mass went, present enduring problems.”1 Tanski et al. also wrote, “Therefore, the majority of the total exhumation in Late Cenozoic [Pliocene] must have occurred before the Colorado River responded [upstream] to integration, and it requires a different source of base level fall.”1

What could have caused the removal of 1.25 miles of sedimentary cover in the Moab, Utah, area and the removal of over 0.62 miles of sediment at Glen Canyon, resulting in the broad planation (leveling) of the land surface? This massive Pliocene erosion event has been a long-enduring problem for conventional geologists, going back to the work of geologist Clarence Dutton in 1882, who labeled this mysterious erosion the Great Denudation.5

What caused the Great Denudation that ended in the Pliocene? And what might have caused the hiatus in erosion at the end of the Pliocene and during the earliest part of the Ice Age (early and mid-Pleistocene)? Before we suggest answers for these questions, let’s examine the results of the second study.

Emmanuel Gabet of San Jose University examined the canyons of the central Sierra Nevada Mountains, including Yosemite Valley.2 He determined the present rivers are too small to have carved the massive and deep canyons in the central Sierra Nevadas, so he postulated that there must have been a lot more water flowing through these canyons in the past, particularly prior to the Ice Age, in the Miocene and Pliocene.2 But there is little evidence of this massive river today.

His interpretation of this supposed missing river system is supported by thick and extensive volcanic-rich sediments found in the Central Valley.2 He suggested these volcanic rocks were transported by the missing river. And yet, there are no volcanoes in the central Sierra Nevadas to supply the volcanic sediment. Gabet told Live Science, “You’ve got 8 cubic miles [33.3 cubic kilometers] of volcanic sediment deposited in the Central Valley by the Merced River, but you can’t find a scrap of these volcanic [source] rocks in the area around the river.”6

Gabet did locate Miocene and Pliocene (late Tejas) volcanoes in the northern Sierra Nevadas that could have been the source of these sediments. But that would have required long-distance transport by water, hence his proposal of a massive, missing “ghost” river to transport these volcanic sediments.6 All of this water transport and erosion occurred just prior to the Ice Age (Pleistocene). Later, alpine glaciers during the Ice Age scoured and widened these earlier-formed valleys, producing the Yosemite Valley we see today.

Because conventional geologists deny the historical accuracy of Genesis, they operate at a loss. They see evidence of massive erosion and tremendous water flow at the end of the Tejas Megasequence and just prior to the Ice Age but are hampered by their uniformitarian thinking to explain it.

But the Bible gives us answers. Genesis describes a global flood that peaked on Day 150.3 The sedimentary rocks across all of the continents confirm this peak occurred at the end of the Zuni Megasequence (at the K-Pg).3 And the rocks confirm that the Tejas Megasequence records the subsequent receding phase.3,7–10

The massive water erosion that took place in the late Tejas (Miocene and Pliocene) in these two studies is best explained by the receding phase of the Flood. There is no mystery to this erosion. As the floodwater rapidly drained off the continents, we would expect massive removal off the top of the underlying sediments. This unfathomable volume of water draining off the land could have easily transported volcanic material from the northern Sierra Nevadas to the central Sierras. And it could have provided sufficient water to carve massive canyons, like Yosemite Valley.

Likewise, the erosive power of the receding floodwater is the best explanation for the Great Denudation in the central Colorado Plateau. How else could over a mile of sediment disappear from southeastern Utah and the surrounding regions, beveling the surface nearly flat? It also explains the mysterious hiatus in erosion at the end of the Pliocene. Erosion likely ceased after the floodwaters had finished draining off the continents, resulting in a pause in erosion marked by the upper Flood boundary at the N-Q (just prior to the Ice Age).8

The renewed river incision that occurred late in the Ice Age and after was minimal compared to the erosion caused by Miocene and Pliocene flood runoff. And this river incision could have been enhanced by the heavier precipitation in these regions during the Ice Age and increased flow as the ice melted away.3

There is no mystery when the Bible is accepted as truth. Geology only makes sense if viewed within a biblical worldview that accepts the reality of the global Flood.

So what do you frogs think of 5mind.com

It is supposed to be a meme based social network started by LIBERAL HIVEMIND and some other conservative youtubers

I like Hiveminds content enough. It's good for keeping up with the news cycle because he uploads several times a day and his news is about a day late of ours so much faster than any other big media platform or YouTuber

But do you think he has it in him to actually run a social network? And is it potentially taking away views both this Q board and also Truth social should be getting

If any of you are posting there already reply with your usernames so I can follow in case I do register

Can you guys please pray for me?

A Uniquely Designed Air-Filled Sac Within Birds’ Lungs BY FRANK SHERWIN, D.SC. (HON.)
MONDAY, JULY 07, 2025

Soaring birds are a majestic sight to behold, especially when they undergo such climbing and endless spiraling so effortlessly. Not surprisingly, evolutionists see this elegant soaring ability as having originated via deep time and evolution.

Now, an international team of researchers led by University of Florida evolutionary biologist Emma Schachner, Ph.D., has reported for the first time that soaring birds use their lungs to enhance their flying in a way that has evolved over time.1

Dr. Schachner stated, “that breathing is functionally linked to locomotion, and it has been demonstrated that flapping enhances ventilation.”1 She went on to say their

“findings demonstrate that the opposite is also true in some species. We have shown that a component of the respiratory system is influencing and modifying the performance of the flight apparatus in soaring birds, who are using their lungs to modify the biomechanics of their flight muscles.”1

Schachner discovered a unique structure—an air sac—quite by accident while dissecting a hawk. It was named the subpectoral diverticulum, or SPD, and was the subject of her article in Nature.

The subpectoral diverticulum (SPD) is an extension of the respiratory system in birds that is located between the primary muscles responsible for flapping the wing. Here we survey the pulmonary apparatus in 68 avian species, and show that the SPD was present in virtually all of the soaring taxa investigated but absent in non-soarers.2

When viewing a soaring bird, the wings seem to be held in a motionless, horizontal position. Much of this has to do with the birds’ pectoralis muscle and the muscle’s ability to produce force.

The team found that the anatomy of the pectoralis muscle of soaring birds is significantly different from that of nonsoaring birds in ways that improve force generation. Taken together, these results provide strong evidence that the SPD optimizes the function of the pectoralis muscle in soaring birds by improving their ability to keep the wing in a static, horizontal position.1

The case for design is clearly seen in this SPD discovery and research. The scientists in the Nature article said, “The discovery of a mechanical role for the respiratory system in avian locomotion underscores the functional complexity and heterogeneity of this organ system.”2 Even before this study was conducted, the avian respiratory system was not completely understood, such as the bird’s airflow: “Within this vast system of connecting passageways, there are no valves to suggest what the pattern of airflow might be. This has led to much speculation about the roles played by the different parts of the respiratory system”3 and includes the mystery of the amazing syrinx.4

Add to this the “heterogeneity of this organ system” as flight mechanics, respiratory physiology, and locomotion are combined to produce an amazing designed creature of flight.2

Articles in Nature and Phys.org described the SPD discovery in soaring birds as having evolved “at least seven times independently across distantly related soaring lineages.”1 This naturally evolving just once would strain credibility, but Schachner et al. speak of “repeated appearance of the SPD in soaring lineages.”2

There is a better, non-evolutionary explanation for the important SPD. Creationists see it as being placed in soaring birds by the Lord Jesus in the beginning. Dr. Schachner states, “This evolutionary pattern strongly suggests that this unique structure is functionally significant for soaring flight.”1 Creationists respond that the SPD found in soaring birds—and absent in all nonsoaring birds—is functionally designed for soaring flight.

As an eagle stirs up its nest, hovers over its young, spreading out its wings, taking them up, carrying them on its wings… (Deuteronomy 32:11)
