Where you might have a, uh, like a hole in an ice sheet and you get a lot of wash overwash or stuff into the hole in the ice sheet and it leaves a pile of stuff. On the, on the ground, like you can imagine you got an ice sheet, let's say the ice sheet is three, four or 500 feet thick, and you've got this hole that goes to the, to the ground.

And now you've got all of this melting and all of this water is pouring in and the supercharged with sediment. Then you also have Kettle Lakes where you might have like an outwash plain from like the glaciers are there. Seasonally, they will melt in the spring and you'll have this big outwash.

Like if you go to Indiana, you can actually see there's the hummocky moraine that represents the terminus of the ice lobe. And then south of there, it's just flat and you'll see, you'll be driving there and it's very flat. And then all of a sudden it gets hilly. Gets hilly because this is where the, the, the, the moraine is. And the moraine is the, the material that's created by the glaciers.

When they're grinding their way across the land, it pulverizes into the creates this material generally called tail. Until can be structured sometimes, like you'll have terminal moraine at the end of the ice. You'll have, um, recessional moraine where if the moraine melts, if the ice sheet melts back, pauses, it'll build this. this pattern of moraine.

You might have lateral moraine where you might have two mountain glaciers coming together like this. And as those glaciers are grinding their way through the mountain valleys, they're picking up all of this material on the bottom and on the sides. Then when they meet,

It'll form, you'll have this glacier and right down the middle of it, you'll have this big dark streak, which is, which is the lateral mooring, meaning it's on the side. So you've got different kinds, but it's all composed of the same material, this stuff we call till.

So, um, when you look at the tail, there's the other thing that we might get into this here a little bit when we start really looking at the slides is that there's also evidence that you had tremendous high pressure floods moving under the glaciers. So, and they don't have a free surface. So the pressure on the bottom of the water flow is much more conducive to, yeah, this is good.
