I was on my way from St. Louis to Omaha, heading north on 29, and saw some very interesting formations to my right (and quite a ways away on my left). What struck me was how they seemed to jut straight up out of the ground where the surrounding area seems to be fairly flat. Also there seemed to be some pretty steep faces and valleys. Almost like very small mountains.

Anyways, I was wondering what the proper name for this type of landscape was, and if anyone knew how it was formed. To be clear, this was the northern Missouri-southern Iowa border area as seen from hiway 29. This is a very beautiful area IMO.

Thanks.

You're looking at the Loess Hills. What I read on a plaque near Glenwood, this is one of only 2 such hill formations in the world, the other being in China.

Check out this website. Geology of the Loess Hills, Iowa - USGS

If you ever have a chance to travel further north up the I-29/Missouri River corridor, the Loess Hills land formation continues on north to just a ways above Sioux City.
There is some stuning & rugged scenery to be enjoyed in the formation & it is a pretty much unknown feather in Iowa's scenic cap to have these hills.
I own a book titled, "Fragile Giants: A Natural History of the Loess Hills" published by the University of Iowa Press.
