And, uh, Pretty, yeah. This is the kind of thing, when you see this firsthand, it really drives home the scale of these events we're talking about. And then if you follow this South Ryan, you can see that there's all these distributary channels. And then you get down to the mouth there at Soap Lake. South of Soap Lake, you have an outwash plane.

But when you zoom in on, you won't see it here, but put in... Ephrata, E-P-H-R-A-T-A, Ephrata Fan. Let's see, so you've got a couple of thousand square miles of this stuff that you see over on the right, which is When these floods ripped through, creating Grand Coulee, of course, all that material that was formerly part of the bedrock has been ripped out.

And at the mouth of the Coulee, there you can see, you've got hundreds of square miles of that stuff, where it's just massive swarms of boulders. So this was the basalt. that was gouged out in the creation of the coolie.

Yeah. I've, I've lost, I've taken so many tours out here to teach people how to read these landscapes. But one of the, in talking about the terms of the fundamental forces at work, when you've got water flow and let's say you've got a bedrock constriction and that water is flowing through there. And then let's say you, it opens up into a basin, right?

And then let's say you, it opens up into a basin, right?

Well, what happens is that you've got this conservation of flow. As long as the water from the source is more or less unvarying, of course, it did vary. At one point, the water declined. Initially, if you look what's called the flood hydrograph, it's got this steep upward limb with an outburst flood, which would be similar to a dam break flood. And then it has a long tapering tail.

And that's kind of what you saw in this event here. There we go, yeah, see, there we go. The large steep limb that comes first, then you have a longer, slower taping, like second row, second from the left is exactly what I'm talking about. Yeah, you have peak discharge, and then you have this long tail that forms the recession. This is the model of an outburst flood right here.

All of these floods that we're looking at so far are outburst floods. They're coming, it's enormous, almost like a tsunami washing over the land. I mean, literally.
