After further google, it looks like I was right about the formation of the hills in West Mississippi.

quote:
Loess is an aeolian sediment formed by the accumulation of wind-blown silt, typically in the 20–50 micrometer size range, twenty percent or less clay and the balance equal parts sand and silt[2] that are loosely cemented by calcium carbonate. It is usually homogeneous and highly porous and is traversed by vertical capillaries that permit the sediment to fracture and form vertical bluffs.
quote:
The loess along the Mississippi River near Vicksburg, Mississippi consist of three layers. The Peoria Loess, Sicily Island Loess, and Crowley's Ridge Loess accumulated at different periods of time during the Pleistocene. Ancient soils, called paleosols, have developed in the top of the Sicily Island Loess and Crowley's Ridge Loess. The lowermost loess, the Crowley's Ridge Loess, accumulated during the late Illinoian Stage. The middle loess, Sicily Island Loess, accumulated during early Wisconsin Stage. The uppermost loess, the Peoria Loess, in which the modern soil has developed, accumulated during the late Wisconsin Stage. Animal remains include terrestrial gastropods and mastodons.[28]

Loes bluffs

It's very errosove silt that was wind blown and accumulated over thousands of years. That's why kudzu was introduced to slow the erosion down. Mudslides happen often in Natchez. They set up retaining walls and other means to slow it down. Vidalia side is flat due to prevailing wind and the river wants to meander west.
