Bluff Road, Highland Road, the Great Flood of 1927 ??

Did the flood create these ridges, or were they man made? Or neither?

---

Neither. They been around a long time.

I've always thought that was the shoreline many many many years ago. Not really sure though.

You can't be serious? Check out CNN they have them on their site

I'm sure thousands of years of flooding and earth shifting created the ridges

Prairie Terrace. '27 flood did not go over that. Went all the way to the terrace near Opelousas.

I've heard the bluffs came from the dust bowls in the west blowing across the river hitting the cooler air above the river and settling on east banks.

close but not quite correct. the hills in west feliciana were formed this way. correct name is "loess accumulation", wind blown deposits.

highland road is the natural bluff of the miss river. the land on top of the river plain is pleistocene material. it has much more clay than the tunica hills hill material does which is majority silt. ill hold off on commenting about what natchez sits on as im not familiar with it.
