So when you have this peak discharge, so let's assume now the water's flowing and you're in a constricted bedrock confinement, and it's hard bedrock, so the water is less erosive than if it was softer sedimentary rock or unconsolidated sediment. Then it comes into a basin.

Well, if you were to take a transect through the basin and through the channel, the narrow channel, the same amount of water is flowing here as here. Okay. However, it's got to flow faster in the constricted channel. As it flows faster, it becomes more erosive. So when you're looking at a hydraulic event or events like we're looking at here, you have basically two forms.

You have erosion, erosion, and you have sedimentation or deposition. So when I take people through these landscapes, we follow and we go, okay, we can see erosion here now. And, you know, we can actually see, for example, if we're in a bedrock constriction, you can look up and you'll see scouring on the cliff sides.

Then it opens into a basin and boom, now you've got all of this material that's been washed out and dumped. Because as the water slows down, it loses its competency to entrain and transport sediment. So that's what we have here. Now, zoom out once, Ryan, so we can get the big picture of the whole coulee. Stop right there.

Now, do you notice if you go up to, let's see, where it says Elmira and Govan, I believe they're up on Highway 2. Come down, come down, right there. Okay, now, do you see that shaded area that is almost parallel to Highway 2? Just north, it's between upper, right there. That is called the Cooley monocline. There you go.

Now, notice that the Cooley comes in at an angle and then it intersects the monocline. Now, what's a monocline? Now we're talking tectonic forces. If you have compression, let's say, and you have bedrock, Now in the bedrock warps, you can have a down warp. You're compressing. Like if I had a piece of paper, I oftentimes will use that or, you know, that's an anticline. Okay. This is a syncline.

And then if you have a single upwarp, so it's like this, that's a monocline. So you've got compression, syncline. There we go. Let's see what we've got there. Compressional, yeah, compactional monocline formed over inactive base. And yeah, so you've got, those are all examples of monoclines, right? So you have a single upwarp.
