Now, of course, this was completely ignored by geology, which, you know, subsequent to this, Lyellian uniformitarianism became the primary dogma of geology once it became an academic discipline in the late 1800s. And at that point, all references to great floods, deluges, catastrophes was expunged from the curriculum. Why? Well...

It was only a few generations earlier that science had been able to finally dominate over a strictly theological or biblical interpretation. And they say, we're not going to compromise our hard-won, you know, supremacy over the biblical doctrine by going back to deluges and floods and all of that.

And this is why in the 1920s when Harlan Bretts first proposed these great floods out in the Pacific Northwest, they didn't want to hear about it. And it took 25 years before they finally acknowledged and admitted that, you know, Brett's was right. But they then, they imposed upon that an explanation that I think basically straitjacketed any further explanation.

interpretations of what caused this flood. And this is a satellite view here of the Channel Scablands. This is the Columbia Basalt Plateau. You might see upper and lower Grand Coulee. And notice that sort of arc-shaped, darker area to the west of Grand Coulee. You see that? That is called the, that is the Withrow Moraine Plateau.

And that defines the southern limit of what is called the Okanagan ice lobe. And it's so loaded with rocks and boulders and stuff that there's been very little agriculture on it. And so that very distinct arcuate line there is the transition to where south of that is where you have the outwash plain. And that's mostly farms now.

But as soon as you get to the mooring, it's too hummocky and you can't plow it. You can't grow anything on it. So that's kind of right there, that arcuate plain. features the southern lobe. It's called the Okanagan lobe, a part of the Cordilleran Ice Sheet. And you've got those darker areas. You see one coming down there about the middle of the screen. That's called the Telford Scabland Tract.

And when Bretz discovered this, he assumed that it was a discharge. That's the Columbia River coming down, like from... just center right, makes a sharp bend to the west, goes over, and then you can see where Grand Coulee starts, and then the Columbia arcs to the north and then back to the south. He assumed that this was water discharging from the ice sheet right there at that great bend region.
