What kind of scale are we talking about? Like the river moved 50 feet? Or 5 miles?

Rodney MS located on the banks of the Miss river was once a thriving metropolis and was even in the running for the state capitol of Landmass back pre-civil war. Then the Civil War happened. Then a few years later the river up and shifted 2 miles making the town and port of Rodney useless. The town is now thicket and hunting camps.

A Presbyterian college was near Rodney that all the landed gentry who stayed home for college went. It was in fact what Ole Miss falsly leads Itself to believe it is now. Was called Trinity college? It was bought by the state after the civil war and is now Alcorn. The old chapel is still standing.
Edit- the college was called Oakland College.

Not sure about the college, but the church is indeed still standing and still has the cannon ball stuck in it.

That view shows an oxbow lake (the long slender body of water). The furthest west one was probably around where one of the oldest large channels was.
So, miles.
But remember that all rivers around here drain to the Mississippi...and much of the southern part of Louisiana didn't exist until the Mississippi dropped sediment there building out the land a la:

There went an hour watching youtube videos about Rodney and whats left of it now. Thanks, guys. I got stuff to get done today. No more posting interesting historical stuff. Cool? Cool.

North of Vicksburg the delta is on both sides? Haven't been on the Arkansas side of the river there.

West Helena,ARK has some hills. But it's set back off the river a good ways from what I remember. Been many years

you guys didn't take GEOL?

I've heard it was the prevailing winds over a long period of time blowing dust/dirt in the atmosphere from the Great Plains in the west. As the dust crossed over the river, the moisture caused it to drop out on the east side creating the hills.

I don't think there was any question about the cause of the alluvial flood plain, just the hill formation on the other side.

The process that makes the difference was the movement of the river. Not unlike why Marksville has hills. The Red took the Moncla gap and never cut those. Or cut there so long ago that new deposits have formed.

I don't know man. I thought he was wanting to know what made the hills. It's pretty obvious what made the flat land. Either way the topo in that area is interesting to me.

Your main point is correct, but I've always found it interesting that pretty much none of the rivers in LA drain to the Mississippi.
The Red did at one time, but now that water goes down the Atchafalaya. Only a very small portion of rain that falls in LA actually ends up in the Miss River.
